When they were joined by Plumier in 1721 they worked together on a number of marble funerary monuments, including that of John Sheffield, duke of Buckingham (1721–22, London, Westminster Abbey) After Plumier died soon after his arrival in 1721, Delvaux and Scheemakers are believed to have collaborated with Francis Bird on the marble monument to John Holles, 1st Duke of Newcastle, also in Westminster Abbey. While in Rome, John Russell, 4th Duke of Bedford, commissioned a number of works inspired by antique examples, most notably Caunus and Byblis. This group is a free version of a sculpture by Pierre Le Gros the Younger of some 20 or so years earlier where Le Gros had deliberately added heads, hands and legs to a fragmented antique group of Amor and Psyche in such a way that it turned the love story on its head and instead of Amor showed Caunus as he vehemently defends himself against the sexual advances of his sister. He also made a marble funerary monument for the Van der Noot family in 1746– for the Carmelite Church in Brussels and which is now in the Rijksmuseum. For the palace in Brussels, which survives partially, he created allegorical reliefs for the façade and the staircase and free-standing statues, including a marble Hercules at the foot of the stairs.
