The Donor Figure in this panel, here attributed to Francesco Ubertini called Bacchiacca (1494-1557) represents an old man kneeling as he offers up a ruined building on a plot of land, possibly a church to be renewed. He is seen in profile against a dark green hanging of rich fabric. The figure forms a pair with a second panel in the Portsmouth collection (210/1975/2) representing a young man in a similar pose. The two panels appear to have formed the end sections of the predella panel for an altarpiece.

The elderly donor is dressed in bright red stockings, he wears a pale yellow shirt and cloak with a faded burgundy over mantel bound tight at the waist by a blue-grey cloth belt. Seen from behind, he rests his left hand on his knee while in his right he raises up his offering, his head his turned over his left shoulder to reveal his balding pate and long white beard. The bold colouring and striking contraposto pose of the figure identify the painting as the work of a Florentine Mannerist influenced by Jacopo da Pontormo (1494-1556) and Andrea del Sarto (1486-1530). The old attribution to Bacchiacca inscribed in an old script on the reverse of the panel appears convincing: Bacchiacca was a versatile and eclectic painter who was apt to use the bright colouring and the compositional solutions of his contemporaries, particularly during 1530s. He specialised as a painter of small figures and on occasion produced predella panels for altarpieces by other artists. Vasari (1511-1574), who probably knew Bacchiacca, claimed he was a pupil of Pietro Perugino (c.1445/50-1523) and a friend of Andrea del Sarto, with whom he also had occasion to collaborate alongside Franciabigio (1484-1525) and Pontormo; from about 1540 Bacchiacca was court painter to Duke Cosimo I de’Medici.
