Francesco d'Ubertino Verdi, called Bachiacca; is also known as Francesco Ubertini, il Bacchiacca (1494–1557). He was an Italian painter of the Renaissance whose work is characteristic of the Florentine Mannerist style. Bachiacca was born and baptized in Florence on 1 March 1494 and died there on 5 October 1557.
Bachiacca apprenticed in Perugino's Florentine studio, and by 1515 began to collaborate with Andrea del Sarto, Jacopo Pontormo and Francesco Granacci. In 1523, he again participated with Andrea del Sarto, Franciabigio and Pontormo. While he established a reputation as a painter of predellas and small cabinet pictures, he eventually expanded his output to include large altarpieces.
In 1540, Bachiacca became an artist at the court of Duke Cosimo I de' Medici and Duchess Eleanor of Toledo. In this capacity, Bachiacca was a colleague and peer of the most important Florentine artists of the age.
Bachiacca's first major commission was to paint the walls and ceiling of the duke's private study with plants, animals and a landscape, which remain an important testimony of Cosimo's interest in botany and the natural sciences. More on Francesco d'Ubertino
It would seem that the Strüb brothers specialised in large-format, carved wooden altarpieces although none have survived in their original form. It is thought that they were also responsible for designs for sculptures, which they may also have executed themselves. The third brother, Pieter, who was much younger than Jakob and Hans, has recently been identified as the Master of Messkirch. More on The Strüb family
