Origins The origins of the Trissino family are lost in the
Early Middle Ages. Various historians and scholars between the 17th and 19th centuries outlined several possible hypotheses, based also on the interpretation of numerous documents preserved by the Trissino family themselves. Bernardo Morsolin, in his monograph on Gian Giorgio Trissino, he agrees with the claims of Giambattista Pagliarino,) and built the ancient castle of Trissino, which later gave its name to the town and the entire valley. The historian Gaetano Maccà in his essay regarding the existence of an ancient
mint in Vicenza reconstructs the events of Nicolò Trissino, son of Paolo, who in 1013 was elected Governor of Vicenza and confirmed in office by Emperor
Henry II with the authority to mint coins bearing the
coat of arms of his family, a privilege later extended by
Conrad II. Traditional accounts, however, claim that the Trissino descend from a legendary hero, Achilles, son of Alcasto, who lived in the city of
Troezen in the
Peloponnese. At the age of eighteen, he reportedly followed the general
Belisarius to Italy during the
Gothic War. After the conflict, Achilles is said to have settled in the Valle di Trissino, which was named in memory of Troezen, thus laying the foundations of the family. Gian Giorgio Trissino included the exploits of these figures in his epic poem ''L'Italia liberata dai Goti
of 1547, set during the Gothic War. In 1624, Paolo Beni reconstructed the family’s lineage in his Trattato dell'origine et fatti illustri della famiglia Trissina
, in which he cited an ancient document tracing the family’s history, starting with Achilles. The theory of Greek origin is supported by Giovanni Pietro Romani in Corona della nobiltà d'Italia
, who considers Paolo Beni’s narrative confirmed by the discovery of coins among the ruins of an ancient house in Castelvecchio di Valdagno, depicting figures in ancient Greek attire with the inscription of the Nobles of Troezen
. The traditional lineage of the early Trissino is further detailed in an 18th-century manuscript by Parmenione Trissino, preserved in the so-called Trissino Archive'' – Trissino dal Vello d'Oro deposit of 1919 – at the
Biblioteca Civica Bertoliana in Vicenza. The most representative figures of the traditional lineage are: • Alcasto, likely born in 482 AD, married Ericinia, daughter of Timoteo, lord of
Athens; • Achilles (506–559), son of Alcasto, cupbearer to the
Byzantine emperor Justinian I and captain in the war against the
Goths, settled in the lands between the Agno and Chiampo rivers, married Carienta, daughter of Verulando, a subdued Goth, and had two sons: Giustino and Verulando; • Giustino (545–608), son of Achilles, married the daughter of the lord of Castelgomberto, thus expanding his domains; • Bonifacio, son of Ulieno, married Gisulfa, daughter of
Gisulf II, Duke of Friuli; • Alessandro, son of Alcasto, captain of the ships of
Maritime Venice during its revolts against the
Exarchate and the
Lombards (7th century), married Alessia, daughter of
Orso (d. 737), third
Doge of Venice; • Giorgio, son of Alessandro, the first with this name, lived 103 years; • Antonio, son of Claudio, whose possessions in
Chiampo and
Arzignano were devastated by the
Hungarians (9th century); • Corrado, son of Antonio, fought for
Henry, Duke of Bavaria, brother of Emperor
Otto the Great (10th century); • Nicolò, son of Paolo, appointed imperial vicar, minted coins at the city mint in the 11th century, as cited by Gaetano Maccà in his work
Della Zecca Vicentina, 1802; • Eugenio, son of Nicolò, lived 48 years. Exiled from Vicenza in 1054, he may be the possible progenitor of the Trissino da Lodi family. • Enrico, son of Olderico, "
served under Rodolfo, son of Emperor Henry"; • Olderico II, son of Teobaldo, hosted
Frederick Barbarossa on November 3, 1154, who confirmed the lordship over the lands of the Valle dell'Agno and the title of
count; • Olderico III, son of Uguccione, the first figure with recognized primary documentary evidence.
Middle Ages The first family member with historical evidence from primary sources was Olderico (Olderico III according to the family historiography compiled by Parmenione Trissino), son of Uguccione. It is documented that Olderico was among the Vicentine nobles who received the oath of allegiance from the Commune of
Bassano in 1175. According to a study analyzing the rapid economic growth in the second half of the 12th century driven by the Trissino family, it is hypothesized that Olderico may have been the founder of the village that is now the city of
Valdagno. Based on the oldest documents available today, it appears that around the year 1000, power in the Valle dell'Agno was managed solely by ecclesiastical entities, such as the Vicentine
diocesan chancery and the Veronese monasteries of
San Zeno and
Santa Maria in Organo. The Trissino family’s skill likely lay in their ability to navigate between major powers (Empire and Church) to increase their influence. By the 11th century, it is plausible that they were part of the Vicentine
curia vassallorum. The earliest recorded episcopal
investiture received by the Trissino family dates to 1219, referencing an earlier one, likely granted by Bishop Pistore to Olderico in the second half of the 12th century. Feudal investitures included extensive rights and jurisdictions, such as tax collection, justice administration, appointment of deans, and grazing rights. The fact that Grifolino, son of Olderico, is mentioned in the 1208
Building Decree, cited by Giovanni da Schio, as the owner of the
turris domus grandis near the
Vicenza Cathedral (the same area where Palazzo Trissino al Duomo was built three centuries later), may further testify to the close, even political, ties between the Trissino family and the diocesan chancery. a member of one of the city’s leading families, evidence of the strong relationships forged by the Trissino family with representatives of imperial powers (at that time, Verona was the capital of the
March of Verona, a subdivision of the Holy Roman Empire encompassing the
Triveneto region). From Chiara, Olderico had eight children, four of whom are considered progenitors or
colonels of their respective branches: • Miglioranza (Miglioranza branch); • Paninsacco (Paninsacco branch); • Arnoaldo (Dalla Pietra branch); • Corrado (Castelmaggiore branch). The latter two participated only marginally in Vicenza’s political life: the Castelmaggiore branch became extinct with Corrado’s four children (13th century), while the Dalla Pietra branch is known only until the 15th century (with Bugamante, Giacomo, and Pierantonio, sons of Antonio di Giacomo). The castles in the Trissino area during the 11th–13th centuries are attributed to these family branches: •
Castel Maggiore to the eponymous branch, located on the summit of Monte San Nicolò, with remnants still visible today; upon the extinction of this
colonel in 1284, its fiefs and assets were divided between the Paninsacco and Dalla Pietra branches; •
Castel Antico to the Paninsacco branch, identified on the Colle dell’Angelo, where the Trissino cemetery now stands, more recently called
Bastie; •
Castel della Pietra to the eponymous branch, corresponding to the area of the current Villa Trissino Marzotto; in 1427, upon the extinction of this branch with Giacomo Trissino della Pietra, the castle and lands passed to Nicolò il Grande, son of Cristoforo Trissino of the Miglioranza branch. Other medieval castles built in the Valle dell'Agno and associated with the Trissino family include: built in 1212, originally incorporated into the castle itself, located in Maglio di Sopra, strategically overlooking the Agno stream valley, and witnessing the Guelph-Ghibelline conflicts in which many Trissino members were involved; • The Valdagno castle, located between San Clemente and Contrà Castello, of which nothing remains, belonged to Miglioranza Trissino, a Ghibelline and elder brother of Paninsacco, a Guelph; • The
Brogliano castle, about which little and fragmentary information exists and which disappeared early; • The Quargnenta castle, mentioned in the diploma granted by
Frederick II to the Trissino family in 1236; • The
Castelgomberto castle, referenced as early as the diploma of
Otto III around the year 1000; • The
Cornedo castle, also belonging to the Trissino Miglioranza branch, cited in Otto III’s imperial diploma and later granted as a fief by the bishops of Vicenza; in Cornedo was the country villa of
Gian Giorgio Trissino, a descendant of Miglioranza. None of these castles survived intact beyond the 14th century. Until the 13th century, the Trissino family’s seigneurial prerogatives amounted to absolute control over the territory, exercising authority over people and property and managing their fiefs almost as an autonomous small state, thanks to their own army and feudal rights covering key aspects of inhabitants’ lives: water, mills, grazing, and markets. However, the assets described in Olderico’s 1212 will were divided only between the two main
colonels of the family: Miglioranza, a Ghibelline, and Paninsacco, a Guelph. In the
Middle Ages, the Trissino family, managing a substantial collection of lands, castles, fields, forests,
tithing rights, etc., agreed on the communal use among the various family branches to better preserve their holdings. For example, in 1343, sixteen Trissino household heads (
consortes) were recorded as jointly holding a single episcopal fief. To preserve the patrimony, the sense of a single lineage (
domus et progenies) took precedence over personal disputes or political alignments. Despite being adversaries, supporting the Guelphs and Ghibellines respectively, brothers Paninsacco and Miglioranza Trissino signed an agreement on December 21, 1224, binding also for their children and successors, stipulating that all sites suitable for fortresses, tithes, and other feudal rights were to be held and used jointly by the two
colonels. Against the backdrop of the 13th-century events that saw the dominance of the Paduan Guelphs in Vicenza, followed by the Veronese Ghibellines from 1312 to 1387 with the rise and fall of the powerful
Ezzelino family and the subsequent rise of the
Della Scala, Miglioranza, Paninsacco, and their respective families did not refrain from fighting, aligning with opposing factions. In 1230, Paninsacco Trissino rebelled against the ban of the Vicenza
podestà and barricaded himself in his castle. The following year, the municipal army stormed the fortress, and Paninsacco was stripped of his assets. Later, the Miglioranza branch faced a similar fate when, in 1236, they were banished from the city, and their urban tower-houses were looted. Later, in the conflict against the Paninsacco branch, in 1291, Enrico Trissino Miglioranza was defeated and beheaded, ending the war. However, at the dawn of the 14th century, under Scaliger domination, Morando Trissino Paninsacco was defeated by the Veronese Ghibellines and stripped of his fief. Meanwhile, in 1231, Bishop Manfredo of Vicenza confirmed the Trissino family as lords of their lands, by virtue of a prior papal privilege granted by
Pope Urban III. Furthermore, with a diploma dated April 4, 1236,
Frederick II not only reaffirmed the Trissino family’s
titles but also granted them the use of the
imperial double-headed eagle in their coat of arms, in recognition of their loyalty to the Empire during those events. The wars and shifting alliances ultimately did not undermine the Trissino family’s dominance in their valley, though they transformed into urban aristocrats. The most significant exception occurred during the brief Visconti domination at the end of the 14th century, during which the Trissino family (including Gian Giorgio, grandfather of
Gian Giorgio Trissino) had to reconquer their lands, fighting the occupiers led by the
condottiero Niccolò Piccinino.
From the Renaissance to the late 18th century From Paninsacco Trissino, who lived in the 13th century, descends the Trissino Paninsacco branch, whose descendants still inhabit the eponymous villa in the municipality of Trissino – one of the rare cases in Veneto where a noble residence has remained in the same family’s ownership for centuries. The elder brother Miglioranza, who married Anna Porto and later Caterina Vivaro, is the common ancestor of other Trissino branches that developed in subsequent centuries, namely: • Trissino di Riale (named after the district in Vicenza where their palace was located), extinct by the end of the 18th century; • Trissino Baston (whose palace on Corso Palladio in Vicenza serves as the town hall), extinct by the mid-19th century; • Trissino di Sandrigo (descendants of Lodovico di Bartolomeo, who married Angela Verlato, daughter of Pietro, a landowner in that area, in 1435), extinct when the last member, Irene di Giustino, married Gaetano Trissino dal Vello d'Oro in 1712; • Trissino dal Vello d'Oro, an addition to the surname authorized in 1515 by
Maximilian I for
Gian Giorgio, the renowned poet and humanist, a branch still extant. Based on documents in the Trissino dal Vello d'Oro Archive at the
Biblioteca Civica Bertoliana, the following
family tree can be reconstructed: Only the descendants of Gian Giorgio Trissino dal Vello d'Oro used the full surname with the
nobiliary particle, while members of other Trissino branches always signed with the simple surname without any title, sometimes making it challenging to accurately identify familial connections when given names were repeated across branches. On April 28, 1404, the city of Vicenza
voluntarily submitted to the
Republic of Venice, and on September 3, 1406, the
Doge Michele Steno confirmed the Trissino family as counts, knights, and lords of the lands of the Valle di Trissino and the
fiefs subsequently added, although landed properties, tithes, and minor jurisdictions had to be repurchased.
Economic development The entry into the so-called
Domini di Terraferma brought a period of relative peace and prosperity to the Venetian inland territories under the Serenissima, lasting much of the 15th century until the events of the
League of Cambrai. This, combined with the great availability of land and resources, prompted the Trissino family to innovate agricultural activities, then focused on cereal cultivation, by expanding irrigated meadows, extending vineyards on hillsides, and promoting sheep farming, including through alpine pasturing. Additionally, other activities developed in the countryside of the Valle di Trissino, such as sawmills for
wood processing, mining and ironworking, millstone production, wool processing, and, from the 16th century,
silk production at the Villa della Colombara in Trissino. The economic and cultural renaissance that followed contributed to the transformation of
feudal families, like the Trissino, from
lords wielding significant power to
patricians, primarily landowners whose rights were now almost exclusively economic. The
Renaissance saw the Trissino family focused on maintaining their privileged positions (many members of various branches served as
Judges of the College between the 16th and 18th centuries). At that time, preserving such substantial patrimony and passing it down through generations was a priority, often through cousin marriages to keep it within the family. The institution of the
fideicommissum was frequently used for this purpose: wills often stipulated the subsequent devolution of the patrimony, typically favoring another family branch if the
testator’s heir had no descendants.
Civil and religious buildings Numerous buildings, country villas, and city palaces reflected the family’s power and wealth: Palazzo Trissino al Duomo (16th century) and Palazzo Trissino Baston (17th century), both designed by
Vincenzo Scamozzi; the two Trissino Villas in Cornedo Vicentino; Villa Trissino in Castelgomberto (15th century);
Villa Trissino in Vicenza (16th century), where the humanist Gian Giorgio Trissino met the young Andrea Palladio; Villa Trissino Paninsacco in Trissino (16th century); the unfinished
Palladian Villa Trissino in Meledo di Sarego (16th century); and, in more recent times, Villa Trissino in Montecchio Precalcino (17th century) and Villa Trissino in Sandrigo (17th–18th centuries). The Trissino family was among the Vicentine patrician families that most cultivated the arts, reaching its peak with the relationship between Gian Giorgio Trissino and Andrea Palladio. The oldest recorded is the church of Santa Maria in Paninsacco built in 1212 by Paninsacco Trissino as an appendage to his Valdagno castle. Later, in March 1380, Niccolò Trissino il Grande inaugurated the new parish church of Valdagno, dedicated to Saint Clement, whose Conception chapel was dedicated to the family and housed his equestrian tomb until 1797. Every town’s parish church had a chapel reserved for the Trissino family, or at least an altar, while the countryside featured chapels and oratories where various family members chose to be buried. An example is the oratory of Santa Maria Assunta in
Sandrigo, built in 1610 in the town’s main square (now Piazza Garibaldi) by Canon Serrano di Alvise Trissino da Sandrigo as a family chapel. It was restored in 1843 under the supervision of Count Gian Giorgio Trissino dal Vello d'Oro by the architect Antonio Caregaro Negrin in its current Gothic style, likely using materials from the
Cricoli villa, such as the columns of the external portico. The Trissino family’s presence in the
Vicenza Cathedral was equally significant, with plaques and tombs, now largely lost due to World War II bombings. Gaspare Trissino, father of
Gian Giorgio, in his 1483 will donated funds for the embellishment of the sacristy and the adjacent chapel on the left side of the cathedral. Other significant traces in the city are found in the small church of Saints Philip and James in Contrà Riale (now part of the Bertoliana), in the churches of San Giuliano, Santa Corona, and San Lorenzo, the latter being the preferred church of the Trissino dal Vello d'Oro branch. The first Trissino members whose presence in military episodes is historically verified appear during the wars between
Guelphs and Ghibellines, which, from the 12th to the 14th centuries, shaped the history of many Italian communes in defining territorial power struggles. Several Trissino family members, starting with brothers Miglioranza and Paninsacco and many of their children and grandchildren, actively participated, particularly to assert and maintain their power in Vicenza and their territories against both emerging local authorities and other seigneurial families. Significant was the participation in the
Battle of Lepanto by Giacomo Trissino (1541–1571), son of Conte, commanding one of the two galleys funded by the city of Vicenza, ''L'Uomo Marino''. The Venetian ships were the first in the Christian fleet to engage the
Ottoman fleet, setting the course for the epic battle, in which Giacomo, like many other Venetians, sacrificed his life. During the
Eighty Years' War (16th–17th centuries), several Trissino members, especially younger sons, served as
condottieri for the
Catholic Emperor against the Protestant rebels of the
United Provinces of the Netherlands. The first notable figure is Marcantonio Trissino dal Vello d'Oro (1564–1604), second son of Ciro, banished from Vicenza for stabbing Giulio Cesare Trissino in 1583, the alleged murderer of his father. This episode was part of a feud among some family branches after Gian Giorgio Trissino named his second-born son, Ciro, as universal heir, bypassing the firstborn, Archpriest Giulio. For his skills, Marcantonio was appointed military advisor and superintendent of fortresses in
Flanders by the governor of the
Spanish Netherlands, Archduke
Albert VII of Austria. He died heroically on August 21, 1604, during the siege of
Ostend. Also, Attila, second son of Giovan Battista and younger brother of Galeazzo, the commissioner of Palazzo Trissino al Corso, served the Habsburgs, fighting fiercely in
Belgium during the conflicts for the independence of the Protestant United Provinces against the Catholic Spanish government. He died in 1606, and his body was transported to Vicenza for burial in the family chapel. Finally, brothers Alessandro and Francesco Trissino are worthy of mention, sons of Francesco di Antonio, both captains in the Habsburg army and buried in 1689 in the church of Saints Philip and James in Vicenza. A scholar of letters, Gaspare wrote a Latin booklet on the life of Saint Savina Trissino, translated Gian Giorgio Trissino’s tragedy Sophonisba into Latin, and translated the manuscript
Trissinae Familiae Monumentarium into Italian. He died in Trento in 1630. Among the women, the starting point is a saint whose legend spans the 3rd and 4th centuries.
Savina Trissino was a wealthy widow who devoted herself to charitable works, particularly for Christians persecuted under emperors
Diocletian and
Maximian. She cared for
Nabor and Felix, two Roman soldiers who, having embraced the Christian faith, were beheaded near
Laus Pompeia (modern
Lodi Vecchio) in 303. Savina comforted them in prison and later hid their bodies after their martyrdom. According to legend, wishing to bring them to Milan, Savina placed their bodies in a barrel. When stopped by tax collectors, she declared the barrel contained wine or honey. Miraculously, the soldiers found such contents, allowing her to enter the city, where Bishop
Maternus gave them a proper burial. Saint Savina died in Milan on January 30, 311, and her body is preserved at the eponymous altar in the
Basilica of Sant'Ambrogio. The Catholic Church commemorates her on January 30, and her deeds were recorded by Gaspare Trissino, a Somaschi father, and more recently by Francesco Trissino. Key moments of her life are depicted in a frieze painted around 1665 by
Giulio Carpioni (1613–1678), decorating the Council Chamber at Palazzo Trissino, formerly called the Saint Savina Room. Returning to the church of Saints Philip and James in Vicenza, the 1624 painting
Apparition of the Angel to Saint Savina, attributed to Marcantonio Maganza, adorns the left wall of the Trissino chapel. On the right wall is the composition
The Three Venerables of the Trissino House: Sulpizia, Febronia, and Vittoria, painted by
Francesco Maffei between 1630 and 1640. Sulpizia is believed to be the mother of brothers Felix and Fortunatus, born in Vicenza and martyred in
Aquileia in 303 during the purges of Christians from the Roman army. They are recognized by the Church as saints and martyrs. Felix’s body is preserved in the
Basilica of Saints Felix and Fortunatus in Vicenza, while Fortunatus’s, after initial burials in Aquileia,
Grado, and
Malamocco, was transferred in 1080 under Doge
Ordelaffo Falier (whose daughter Anna married the noble Teobaldo Trissino) to
Chioggia, where he became the
patron saint. Febronia, born Elisabetta, was the younger sister of
Gian Giorgio Trissino. She took vows and entered the
Monastery of San Pietro in Vicenza in 1495. From 1518, alongside her fellow nun Domicilla Thiene, she revitalized the Monastery of San Silvestro, founded before the 9th century. == Family conflicts ==
