August and the sybil
XVI century. Wash, Pencil, Pencil ground, Grey-brown ink on yellow paper. Not on displayTraditionally attributed to Nicolò dell´Abate (c. 1512-1571). In the elegantly classical arrangement of the composition, the drawing shows knowledge of the work of Giuseppe Porta, called Salviati (c. 1520-c.1575), but the handling seems nearer to that of Bernardino India, or a close associate. The figures in the background sport curls of hair that are exactly similar to India´s trademark quiff.
