Medina was the son of a Spanish army captain posted to
Brussels, where he was born and later trained by
François Duchatel, before coming to London in 1686 and setting up his studio in
Drury Lane. Even in London he seems to have specialized in Scottish sitters, and in either 1688–89 or 1694 he moved to Edinburgh at the invitation of
David Leslie, 3rd Earl of Leven. He remained there for the rest of his life. He was encouraged and sponsored by
the Earl of Melville, who he painted in London. From 1689 Melville, like many of Medina's subjects a strong
Whig, was Secretary of State for Scotland, effectively running the country for the King in London. With little competition, Medina was the most prominent Scottish portraitist for the rest of his life, charging £5 for a head and £10 for a half-length. His best known works are a group of about 30 oval bust-lengths, including a self-portrait, in
Surgeons' Hall, Edinburgh; these are invariably compared to the
Kit Cat Club series in London by Sir
Godfrey Kneller. His style follows the conventions of Kneller, but his portraits are often more relaxed and informal, favouring relatively bright blues and rose-reds in the clothing, and dark backgrounds. The quality of the painting can vary considerably, probably reflecting the use of his assistants. In 1706 he was knighted, one of the last batch of Scottish knights to be created before the
Acts of Union 1707. Medina died in
Edinburgh on 5 October 1710. He was buried in
Greyfriars Kirkyard in the centre of the city. The grave is a solid enclosed vault on the east side, now appearing half-sunken, adjacent to the steps leading to the northern section. The engraver,
William Howison, is buried in front of the vault. He trained both his own son and the talented
William Aikman, the leading Scottish portrait-painter of the next generation. The
Scottish National Portrait Gallery has a representative ten works, including another self-portrait, and a group of subject pictures bought from his studio by
Sir John Clerk is held at
Penicuik. Most of his paintings remain in Scotland – there are none, for example, in the
National Portrait Gallery, London. ==Illustrations to
