Cecil was a professional soldier who fought in the Dutch War of Independence and in 1610, when his portrait was painted by Mierevelt, led British forces into battle to defend German claims to the duchies of Cleves and Jülich against Rudolf II, Holy Roman Emperor.
Cecil was a professional soldier who fought in the Dutch War of Independence and in 1610, when his portrait was painted by Mierevelt, led British forces into battle to defend German claims to the duchies of Cleves and Jülich against Rudolf II, Holy Roman Emperor. He commanded the first army flagged as British under the Union Flag. The portrait by Mierevelt was painted while Cecil was in Delft and sent back to England. If the present miniature also portrays Cecil, it is possible that it was painted shortly before or after his departure or taken from the oil portrait in Cecil’s absence (who was much missed by Prince Henry during the campaign).
In the 1610s, Peter Oliver was then still much under the influence of his father, Isaac (c.1565-1617), although with an acuteness of observation imparting a lifelike quality that was entirely his own. In the view of Sir Horace Walpole, a connoisseur of portrait miniatures, ‘Oliver’s son, Peter, alone approached to the perfection of his father’. Through his father’s second marriage, moreover, Oliver was well connected to the Gheeraerts family of painters, who commanded the field of panel painting in the early years of the seventeenth century.
Following Isaac Oliver’s death in 1617, Peter Oliver took on his position at court, working as the miniaturist to Henry’s successor as Prince of Wales, Charles (1600-1649). When Charles ascended to the throne in 1625, Peter Oliver was made one of his officers of the chamber. The present work, although early in Peter’s career, is confidently signed in his monogram and represents an important commission from a member of the court’s inner circle.
