Lord Seton is portrayed in the magnificent clothes he wore at the wedding of Mary Queen of Scots and the French Dauphin in April 1558. His baton is that of the Master of the Queen's household, a position he held in 1561, at the age of 27. The portrait was, however, painted later, in the 1570s, the date in the second inscription at the base of the column. Seton was a loyal supporter of the Queen, and acknowledged favourably by her son James VI and I. The coat of arms at the top right is a later addition.
