With intensified excavation in the
Mediterranean in the nineteenth century, terracotta reliefs increasingly came to light in and around Rome, from which original architectural contexts were determined. Metal and marble objects had previously been the most sought by excavators, scholars and collectors, but at this time artefacts in other materials received wider interest, beginning with the late-18th century appreciation of
Greek vases which when they first appeared were thought to represent
Etruscan pottery. (c.1857/58) The first collector to make the tiles items of interest was marchese
Giampietro Campana. His influence and contemporary reputation in archaeology was so great that he was named an honorary member of the
Instituto di corrispondenza archeologica. He published his collection in 1842 in
Antiche opere in plastica ("Ancient works in plastic arts"), in which his findings on the reliefs were first laid out in a scholarly fashion. Thus the tiles became known as
Campana reliefs. Afterwards Campana was sentenced to imprisonment for
embezzlement: in 1858 he lost his honorary membership in the
Istituto di corrispondenza archeologica and his collection was pawned and sold. The terracotta reliefs owned by him are now in the
Louvre in
Paris, the
British Museum in
London and
the Hermitage in
St Petersburg. Other collectors, such as
August Kestner, also collected the reliefs and fragments of them in greater numbers. Today examples are found in most larger collections of Roman archaeological finds, though the majority of the reliefs are in Italian museums and collections. Despite Campana's research, for a long time the reliefs were rather neglected. They were viewed as handicrafts, thus inherently inferior, and not art, like marble sculptures. The idea that they should be treated as important sources for the craftwork of the period, for decorative fashions, and for their
iconography only achieved prominence in the early years of the twentieth century. In 1911
Hermann von Rohden and
Hermann Winnefeld published
Architektonische Römische Tonreliefs der Kaiserzeit ("Roman Architectural Clay Reliefs of the Imperial Period") with a volume of images in
Reinhard Kekulé von Stradonitz's series
Die antiken Terrakotten. This was the first attempt to organise and classify the reliefs according to the emerging principles of
Art history. The two authors first distinguished the main types, discussed their use and considered their development, style, and iconography. The book remains fundamental. Thereafter, apart from the publication of new finds, interest flagged for more than fifty years. In 1968
Adolf Heinrich Borbein's
thesis Campanareliefs. Typologische und Stilkritische Untersuchungen ("Campana Reliefs: Typological and Stylistic Investigations") brought these archaeological finds to wider attention. In his work, Borbein was able to establish the development of the Campana reliefs from their origins among Etruscan-Italiote terracotta tiles. He also dealt with the use of motifs and templates derived from other media and pointed out that the artisans thereby produced creative new works. Since Borbein's publication, researchers have mainly devoted themselves to chronological aspects or the preparation of catalogues of material from recent excavations and publications of old collections. In 1999 Marion Rauch produced an iconographic study
Bacchische Themen und Nilbilder auf Campanareliefs ("Bacchic Themes and Nile Images in Campana Reliefs") and in 2006 Kristine Bøggild Johannsen described the usage contexts of the tiles in
Roman villas on the basis of recent archaeological finds. She showed that the reliefs were among the most common decorations of Roman villas from the middle of the first century BC until the beginning of the second century AD, both in the country houses of the nobility and in the essentially agricultural
villae rusticae. == Material, technique, production, and painting ==
