Flemish painter. Little is known about this artist who in all likelihood belonged to the Flemish artist family, Momper. Long forgotten, Jan de Momper was brought back from obscurity by R. Longhi, who tentatively compiled the artist's oeuvre and who named him "Monsù X". Later, the identification of an inscription on the reverse of a picture in the Chigi collection, Ariccia, lead to the identification of Monsù X as Jan de Momper. He was born in Antwerp, but must have left soon for Italy, where he is recorded in 1657 in Rome. His style reflects his Northern roots, as the brushwork reveals the influence of Joos de Momper; the colour scheme is close to that of Magnasco. //
