[1] The portrait is dated 1638, a time when Sir William Killigrew was involved with partners in an attempt to drain the Lincolnshire fens, an immensely expensive undertaking which caused the family great economic distress, but which did not prevent their commissioning a set of husband and wife portraits.

[1] The portrait depicts the Sir William facing the viewer, leaning against the base of a column.

There is a gold ring tied to his jacket by a black ribbon, the symbolic meaning of which is uncertain.

[1] Van Dyck painted a number of portraits of various members of the Killigrew family during his stay in England.

These include Thomas Killigrew and an Unknown Gentleman, now located in the Royal Collection.
