Baccio Bandinelli, 1493-1560, was Florentine sculptor, whose talent, according to Vasari, was recognized by Leonardo da Vinci, but who was best known - not least because of the way in which he is presented throughout the Autobiography of Benvenuto Cellini - as an envious and malignant man and an incompetent sculptor who hated the success of Michelangelo and of Cellini himself.
Vasari offers faint praise at best in his Life of Bandinelli:
Baccio derived much satisfaction from his Adam and Eve. He expected all artists to be as pleased with them as he was, so he polished them with great care. But once they were unveiled they suffered the same fate as the rest of his work, being lampooned in sonnets and in Latin verses... They are however well proportioned, and though not very graceful they merit considerable praise for their design. ( Vasari, Le Vite, Testo V.267; Life of Bandinelli)
And in another anecdote from Vasari, Bandinelli left a Dead Christ unfinished. When another Dead Christ was put on the altar it was too large and left no room for the priest. Although 'fair and one of the best that Baccio did it was lampooned by the priest as well as the people'( Vasari, Le Vite, Testo V.267; Life of Bandinelli). Ruskin agrees with such assessments of Bandinelli (see Ruskin on Bandinelli).
