The arms are those of the Montefeltro Dukes of Urbino, and this stand must presumably have been made for Guidobaldo da Montefeltro, Duke Guidobaldo I of Urbino (Duke from 1482 to 1508), or someone very close to him. Guidobaldo married Elisabetta Gonzaga, but had no children, so in 1504 Guidobaldo's sister's son, Francesco Maria della Rovere, was adopted as their heir. The form of the Montefeltro arms shown here were in use from 1474, the year Guidobaldo's father, Federico III (1422-1482) was created Duke of Urbino by Pope Sixtus IV, until Guidobaldo's death in 1508.
