Pierre-Antoine Quillard

Pierre-Antoine Quillard, (; – 25 November 1733) was a French portrait painter and engraver who worked in Portugal.

Biography Quillard's father was a woodworker. He began to study art at a very early age, possibly with Antoine Watteau, or at least some of his close associates. When he was ten or eleven, his paintings were deemed such perfect copies of Watteau's style that Cardinal Fleury presented some to King Louis XV, who granted Quillard a pension.

After twice failing to win the Prix de Rome, in 1724 and 1725, and despite having won second place both times, he accepted an offer of work from Charles Frédéric de Merveilleux (d. 1749), a Swiss doctor who was attached to the Royal Court in Lisbon. The position involved drawing illustrations to accompany a herbarium the doctor was preparing.

Because of the huge demand for paintings in Watteau's style that arose after his death in 1721, very few works have been positively identified as Quillard's and a catalogue raisonné has yet to be created.
