Giorgio Vasari, Lives of the Most Excellent Painters… (1850)
“ Jacopo, called l’Indaco, was a disciple of Domenico del Ghirlandajo, and worked in Eome with Pinturicchio: he was a tolerably good master in his day, and, although he brought but few works to completion, yet those few are abundantly worthy of commendation. It cannot, however, be any matter of astonishment, that few works only proceeded from the hands of this artist, since he, being a facetious merry fellow, and a lover of good cheer, who harboured few serious thoughts, would never work but when he was compelled to do so. ”
