Two engravings on mount. 1. A portrait of Alexander Henderson, 1583-1646. Henderons was one of the principal members of the committee which drew up the National Covenant (1638) which marks the beginning of the democratic form of government of the Presbyterian Church of Scotland. 2. A portrait of Archibald Campbell Marquis of Argyle (1598-1661) created from an original portrait in the collection of His Grace the Duke of Argyll at Inveraray. Campbell was a statesman and adviser to King Charles I and a privy councillor, 1626-1637. He supported the Covenanters in their opposition to the King’s policies regarding the National Church. It is thought this was for political rather religious reasons. Later he showed support for Cromwell until the execution of the King, but failed to give full support to Charles II. After the Restoration he was executed in Edinburgh in 1661.
