_Sebastiano del Piombo_ (Venetian: 1485-1547). _See_ 1.
The nimbus around the head indicates the saint; the palm branch and
the pincers indicate St. Agatha, who was "bound and beaten with rods,
and her tender bosom was cruelly torn with iron pincers; and as her
blood flowed forth, she said, 'O thou tyrant! shamest thou not to treat
me so--- thou who hast been nourished and fed from the breast of a
mother?' And this was her only plaint." See also under 20.
