_Martin Ryckhaert_ (Flemish: 1587-1631).
Martin Ryckhaert was a son of the elder, and brother of the
younger, David Ryckhaert. He studied, and for some years
practised his art, in Italy. He is entered in the register of
the Painters' Guild at Antwerp as "a painter with one arm," and
is so represented in the portrait by Van Dyck in the Dresden
Gallery.
