This is a fine example of Cooper's early work of circa 1640.
Sir William Scott, clerk of session, clerk of the privy council and clerk of parliament, was knighted by King Charles I in November 1641. He was a member of the committee of war in 1644, 1646, 1647, and 1649 and was M. P. for Haddingtonshire in 1645. Following the introduction of the Act of Classes in 1649, he was appointed an ordinary lord of session on 7 June 1649, taking the title Lord Clerkington. He died in Edinburgh on 23 December 1656.
