Life
Devis's Death of Nelson
He is noted for being involved in the creation of the posthumous cult of Horatio Nelson. He painted a heroic Death of Nelson, for which he made sketches (including one of Nelson's body during the autopsy by Dr Beatty, the ship's surgeon) on board HMS Victory after her return from Trafalgar[1]. He also painted Dr Beatty, and was commissioned by him to produce a half-length painting of Nelson as vice-admiral, which he lent to Emma Hamilton (who later lost it in an accident whilst travelling). Either the original or a copy of this portrait was exhibited at the Royal Academytwo years after the Battle and many copies were made of it (Lord Howe owned one, and another ended up in the collection of the National Maritime Museum), and it was also engraved in Beatty's account of Nelson's death.
