He was born in Antwerp as the youngest of the four children of Peter (Pieter or Peerke) de Vos, (born in
Leiden in 1490), and Anna de Heere. His father was recorded in the registers of the Antwerp
Guild of Saint Luke in 1507 as a pupil studying painting under Jeroom Scuelens and in 1519 as a free master. Maerten's mother was a daughter of the Antwerp painter Marten (Maerten) de Heere who was registered in 1498 as a free master of the Antwerp
Guild of Saint Luke. Maerten de Vos first trained, along his brother Pieter, under the guidance of their father. The 17th-century Italian artist biographer
Carlo Ridolfi wrote that de Vos worked in the studio of
Tintoretto in Venice, which would explain this influence. In the 1560s an
iconoclastic fury referred to in Dutch as the
Beeldenstorm (Dutch for 'attack on the images or statues') raged in Flanders and reached its peak in 1566. Catholic art and many forms of church fittings and decoration were destroyed by nominally
Calvinist Protestant crowds in the name of the
Protestant Reformation. Floris never recovered from the shock of seeing his artworks destroyed, and soon found himself in a downward spiral in both his personal and professional affairs. He virtually stopped painting after 1566, and a younger generation of artists seized the opportunity to take over his important position in history painting in the Habsburg Netherlands. Among these artists Maerten de Vos became the most prominent. De Vos received in 1570 the commission to decorate the palatine chapel of William, Duke of Brunswick-Lüneburg in
Celle, Germany. His reputation grew and in 1572 he was appointed dean of the Antwerp guild. In 1589 De Vos and
Ambrosius Francken I were appointed by the Ghent magistrate to value the painting of the
Last Judgment by
Raphael Coxie. Their ruling would settle a dispute between the magistrate, who had commissioned the painting, and Coxie, who felt that the sum offered to him was too low for his masterpiece. De Vos and Francken were also chosen as the chief designers of the decorations for the 1594
Joyous Entry into Antwerp of the newly appointed governor of the Southern Netherlands,
Archduke Ernest of Austria. De Vos was further one of the founders of the
Guild of Romanists, which was established in 1572 in Antwerp's
Cathedral of Our Lady. The Guild brought together artists, connoisseurs and humanists who had travelled to Rome and appreciated humanist culture. The diversity of the membership offered artists a good opportunity to network with potential patrons. To meet the strong demand for his work, including from foreign patrons, de Vos developed a streamlined workshop practice. Maerten de Vos had 11 pupils between 1564 and 1599: Balten Vlierden (1564),
Wenzel Coebergher (1573), Hans Snyers (1575), Merten Boly (1577), Jaeckes Keerel (1577), Jan Adriansen Cnottaert (1584), Peeter Goutsteen (1588), Hans Cnottaert (1594), Hans van Alten (1595), Hans de La Torte (1595) and Abraham van Lievendale (1599). His two sons Daniel de Vos (1568–1605) and Maerten de Vos the Younger became painters but their work is hardly known. He died in Antwerp on 4 December 1603 and was buried on 7 December in the cathedral. ==Work==
