Giorgio Vasari, Lives of the Most Excellent Painters… (1850)
“ There is now living in Rome, and certainly a very able artist in his vocation, the painter Girolamo Sicciolante of Sermoneta, of whom, although we have already named him in the Life of Perino del Vaga, whose disciple he was, [1] and whom he assisted greatly in his works at the Castel Sant’ Angelo and elsewhere, it will yet be well to say here also what his merits so amply deserve. Among the first works of Girolamo was a picture twelve palms high, which he painted in oil at the age of twenty, and which is now in the Abbey of San Stefano near Sermoneta, his native place. ”
