Employed as the King's painter in 1536, Hans Holbein the younger painted, in 1537, a mural depicting King Henry VIII, his late father Henry VII, his mother Elizabeth of York, and his then-wife Jane Seymour.
It was considered Holbein's greatest achievement and includes the most well-known depiction of Henry VIII, despite the fact that the mural was destroyed by an accidental fire in Whitehall Palace in 1698.
The original mural survived intact in the Privy Chamber of the palace for 162 years, during which time prints were made of the painting, and in 1667, Remegius van Leemput painted a full copy of the piece, although at a much smaller scale than the mural, which had been life-sized, depicting the four figures at their full height.
A half-portrait of the king by Holbein has survived, as well as the left-hand section of the pencil sketch for the mural. In that era, when preparing for a large painting, artists would generally draw the whole thing out onto paper at full scale and in great detail before commencing the painting proper on board or, in this case, wall.
Most paintings of Henry VIII, including portraits with him as a lone figure, are based, ultimately, upon this lost original.
