Giorgio Vasari, Lives of the Most Excellent Painters… (1850)
“ At the death of Antonio Sangallo, there remained behind him his brother, Battista Gobbo, a man of considerable ingenuity, who had devoted nearly the whole of his time to the buildings of his brother, but was not treated very well by him. This Battista did not live many years after Antonio, and when he died he left all that he possessed to the Florentine Brotherhood of the Misericordia in Rome, but with the condition that they should cause to be printed a book of Remarks on Vitruvius, which he had written. ”
