Giorgio Vasari, Lives of the Most Excellent Painters… (1850)
“ The frieze, which is between the architrave and the cornice in this work, was moreover adorned by Mosca with an exquisite ornament of foliage carved into full relief, and entirely detached from the ground of macigno; this he covered with birds which are so admirably executed that they seem to be flying in the air: it is indeed a marvellous thing to see the tiny legs of those minute creatures, none larger than life, all entirely detached from the stone in a manner that might well be thought impossible: the whole work indeed is more like a miracle than mere art. ”
