He left France in 1728, having carried off the French Academy's grand prix, which provided scholarship for study in Rome.

In Rome, he painted for the Elector of Saxony, Frederick Christian, a "Christ's Visit to the House of Simon the Pharisee",[1] (later engraved by Subleyras himself), this work procured his admission into the famed Roman artists guild, Accademia di San Luca.

[4] Another masterpiece is his painting of St Camillo De Lellis coming to the rescue of the diseased at the hospital of the Holy Spirit.

[5] He was a remarkably incisive portraitist, as evident from the portrait of Pope Benedict XIV[6] or of the obese Cardinal Valenti Gonzaga.

[2] In his illustrations of La Fontaine and Boccaccio his true relation to the modern era comes out; and his drawings from nature are often admirable (see one of a man draped in a heavy cloak in the British Museum).
