_Pietro Lorenzetti_ (Sienese: died 1348).
This painter was the elder brother of Ambrogio Lorenzetti
(1147), and first appears as an artist in 1305. Many of his
works, or fragments of them, may still be seen in and around
Siena. Among the best is a triptych in the sacristy of the
Cathedral representing the birth of the Virgin. "A long series
of frescoes, representing different incidents in the Passion,
have recently been rescued from whitewash in the church of S.
Francesco. They are remarkable for their vigour and harmony,
and show Pietro to have possessed great talents both as a
colourist and as a draughtsman" (Bryan's _Dictionary_).
Probably illustrative of some incident in the life of a saint--of
Bishop Sansovino, perhaps, the patron saint of Siena--in which the
forces of the Christian and pagan religions were opposed. On one side
is a pagan priest bearing a statue, supposed, from the apple in its
hand, to be that of Venus. On the other is a Christian bishop engaged
in some ecclesiastical function.
