_Francesco Mantegna_ (Paduan: about 1470-1517.)
_See 639._
For the subject, see 576. Notice the pool in the foreground on which
are two water-fowl, while a tortoise crawls towards it. This picture is
the same size as 639 and 1106, and the three beautiful little panels
doubtless formed a series--now at last brought together again, having
been long separated in three different collections.
