Portrait of Queen Henrietta Maria, as St Catherine

The portrait of Queen Henrietta Maria, as St. Catherine of Alexandria was painted by van Dyck around 1639. She is depicted in a red dress, wearing a coronet and holding a wheel representing the wheel used to torture St Catherine of Alexandria.

There are numerous copies of the portrait, one of which was sold at Bonhams for £9,000 in October 2004.[1]

Another copy, dated 1649, by Matthew Snelling, is in Alnwick Castle.[2]

Portrait of Queen Henrietta Maria from Philip Mould collection before restoration

The portrait featured in the BBC TV programme, Fake or Fortune?.[3][4] Philip Mould owned a portrait of Queen Henrietta Maria in a blue dress. This had been sold at Christie's on 24 January 2012.[5] At that time it was described as being "after van Dyck". It was estimated at £4,000 - £6,000 but realised £8,750 (including buyer's premium).

An X-ray suggested that Mould's portrait contained a smaller original which had been enlarged and over painted in the 18th century.[3][6] Removal of the over-painting revealed an unfinished portrait of the Queen as St Catherine, which was subsequently attributed to Van Dyck at the conclusion of the programme by Dr Christopher Brown, director of the Ashmolean Museum and an authority on van Dyck.[3]

Following the programme, the restored portrait went on display in the Banqueting House, Whitehall, where Henrietta once lived.[3][7]
