Bernardo Vecchietti, one possible author, was the son of a rich cloth merchant and would only have been in his early twenties when he compiled the manuscript in the early 1540s. He was later a patron of the sculptor Giambologna, and helped Duke Cosimo organize his artistic projects, in 1572 provoking bitter complaints by Vasari, surviving in a letter to Vincenzo Borghini (another figure suggested as the Anonimo Gaddiano).[12]
