Several of Poussin’s finest works are in this country. In the Dulwich Gallery there is, we believe, the largest number to be found in any one collection. Among those, the subject of the Angels appearing to Abraham is treated with considerable grace and beauty. The picture of Moses striking the rock, in the possession of the Marquis of Stafford, is one of Poussin’s most profound and elaborate performances; and, in the National Gallery, the two Bacchanalian subjects will furnish a full idea both of his powers and deficiencies in treating that favourite class of compositions. The reader will find a more detailed account of the life and works of Poussin in Lanzi’s ‘Storia Pittorica dell’Italia,’ and Bellori’s ‘Vite di Pittori moderni.’ There is an English life of him written by Maria Graham. Much critical information concerning his style and performances will be found in the writings of Mengs, Reynolds, and Fuseli.

He was the eldest of nine children; of the rest little more is known than that several of the brothers were among the most eminent merchants in the city of London during the reigns of the two first Stuarts. His father, Thomas Harvey, followed no profession. He married Joanna Falke at the age of twenty, and lived upon his own estate at Folkstone. This property devolved by inheritance upon his eldest son; and the greatest part of it was eventually bequeathed by him to the college at which he was educated. At ten years of age he commenced his studies at the grammar school in Canterbury; and upon the 31st of May, 1593, soon after the completion of his fifteenth year, was admitted as a pensioner at Caius College, Cambridge.
