"Little Barrel" was the nickname given to which artist?

Alessandro di Mariano di Vanni Filipepi (c. 1445 – May 17, 1510), known as Sandro Botticelli, was an Italian painter of the Early Renaissance. Botticelli's posthumous reputation suffered until the late 19th century, when he was rediscovered by the Pre-Raphaelites who stimulated a reappraisal of his work. Since then, his paintings have been seen to represent the linear grace of late Italian Gothic and some Early Renaissance painting, even though they date from the latter half of the Italian Renaissance period.

The nickname Botticelli, meaning "little barrel", derives from the nickname of Sandro's brother, Giovanni, who was called Botticello apparently because of his round stature. A document of 1470 refers to Sandro as "Sandro Mariano Botticelli", meaning that he had fully adopted the name.
