According to an account of gold mining in Scotland by Stephen Atkinson written in 1619, Bronckorst was working in London as an associate of the English painterNicholas Hilliard. With a third painter, Cornelius de Vos, they went to Scotland to invest in gold mining, meeting Regent Morton. According to Atkinson, Hilliard invested in the mine, and Bronckhorst was in Edinburgh negotiating the sale of gold to the mint, unsuccessfully, but he was hired by Morton to paint portraits "great and small" of the young king. The involvement of Hilliard has been doubted by some of his biographers. Cornelius de Vos is recorded as a mineral prospector in Scotland for gold and salt in this period, not a painter. There is a record of a 'French painter' who made a portrait of the Kingin September 1573, during Morton's regency, for £10. Cornelius de Vos was made to review and lost his contract in 1575, which may reflect Atkinson's description of Bronckhorst negotiating with Regent Morton on behalf of de Vos.
Paintings and records
In Scotland, Arnold painted the King, Regent Morton, George Buchanan, and the Earl of Arran. According to the inventories of the Earl of Leicester, the earl had a portrait of the 'young king of Scots' in 1580, which may have been a copy of Arnold's picture. Leicester sent his own portrait to James VI, painted on canvas by Hubbard in 1583. Arnold was paid £130 Scots for portraits of James VI in April 1580. Sittings for the King's picture by the "Flemish painter", probably Arnold, at Stirling Castle during the difficult political circumstances in 1579 were mentioned in letters sent to George Bowes in England, the brother of the diplomat Robert Bowes, by Archibald Douglas. The portrait, a "portratur", was destined for Robert Bowes to give to Queen Elizabeth. Archibald Douglas supervised the painter and the sittings, and sent the picture to England;
The Flemish painter is in Stirling, in working of the King's portraiture, but expelled forth of the place at the beginnings of thir troubles. I am presently travelling to obtain him license to see the King's presence thrice in the day, till the end of his work; quhilk will be no sooner perfected nor nine days, after the obtaining of this license... the king our sovereign's portraiture, according to his proportion in all parts, which has been so long in making, and so difficult in getting, that I have been almost wearied therwith.
A son of George Bowes, also called George, was later sent into Scotland as a mineral prospector at Wanlockhead in 1603 with Sir Bevis Bulmer, which may relate to Stephen Atkinson's gold-mining story. By September 1580, Arnold had completed a half and full length of the king and a portrait of George Buchanan for £64. After receiving £46 for portraits of James on 6 September 1581, on 19 September 1581 Arnold was appointed to the post of King's Painter, the first such appointment in Scotland. He received a privy seal letter of appointment guaranteeing the payment for life of £100 yearly from the "reddiast of his hienes' casualties and cofferis," meaning the treasurer was to make Arnold's payment a priority. The privy seal letter and account entries describe him as a flemyng. Bronckorst returned to London in 1583 where he disappears from view. He was succeeded as court painter in Scotland by another Flemish artist, Adrian Vanson, who was subsequently appointed King's Painter. One portrait signed and dated 1578 by Bronckorst survives; the English sitter Oliver St John of Bletso, was the father of a reluctant keeper and juror of Mary Queen of Scots.
