Accounts of his work mention that he was an "English man". He was a
burgess of
Glasgow. In 1627 he painted the globe and the weather vane of the steeple at the
Glasgow Tolbooth. , heraldic painting attributed to Valentine Jenkin is shown as a palimpsest with earlier work. Jenkins redecorated the Chapel Royal at
Stirling Castle in 1628, refreshing painted decoration from 1594 inside and out. Within the chapel, a painted frieze with festoons of leaves and fruit and (now blank) medallions, is his work. The frieze was described in 1628 as a "course of panels, arms, and badges conform to the roof and border". The painted freize is visible (with some restoration) within the chapel. It includes an "IR6" monogram for James VI. External paintwork has left discernible traces and shadows on the courtyard façade. Materials bought for Jenkin and his team of painters at Stirling in 1617 included,
red lead, florey (a kind of
indigo),
umber, linseed oil, skins for making glue size, butter, and jars called "pigs". In 1628 he was bought chalk, oil, and colours. Jenkin made two contracts for painting the rooms of the palace of Stirling Castle and the Chapel Royal in 1628. On the exterior of the palace he gilded and painted the royal initials and crowns, and painted the window grills or
yetts with red oil paint. Details on the gatehouse and its coat of arms were painted the same. Inside, the window shutters were painted, and he restored the existing painted borders and royal ciphers. He marbled the chimneys. The queen's bedchamber was to be "fair wrought with arms and antiques" according to the ceiling details. He also painted the rooms and passages on the floor above, including two rooms for the
Duke of Buckingham which were above the king's bedchamber, accessible via a private stair. The upstairs rooms were painted gray and white, with imitation panelling in the passages. Nothing survives of this work, although nearly all the rooms mentioned in Jenkin's contract survive.
Falkland Palace Jenkin rode from Stirling to paint and gild three great carved oak heraldic panels for the exterior of the gate house of
Falkland Palace in 1629. The wooden armorials today are 19th-century replacements.
Kinneil House A vaulted first-floor room at
Kinneil House, known as the Arbour Room, was redecorated around the year 1620 for
James Hamilton, 2nd Marquess of Hamilton and his wife
Ann Cunningham. Her "shakefork" and the rabbit supporters of Cunningham heraldry can still be seen. This painting was almost certainly the work of Valentine Jenkins, who worked for the family elsewhere. == Heraldic manuscript ==
