Few sources of acquisition within the limits which he had laid down for himself escaped Mr. Payne KNIGHT’S research. He kept up an active correspondence with explorers and dealers. He watched Continental sales, and explored the shops of London brokers, with like assiduity. Coins, medals, and gems, shared with bronzes, and with the original drawings of the great masters of painting, in his affectionate pursuit. In his search for bronzes he welcomed choice and characteristic works from Egypt and from Etruria, as well as the consummate works of Greek genius. His numismatic cabinet was also comprehensive, but its Greek coins were pre-eminent. For works in marble he had so little relish that he actually persuaded himself, by degrees, that the greatest artists of antiquity rarely ‘condescended’ to touch marble. But he collected a small number of busts in that material. For one volume of drawings by CLAUDE, Mr. KNIGHT gave the sum of sixteen hundred pounds. Among his later acquisitions of sculpture in brass was the very beautiful _Mars_ in Homeric armour. This figure was brought to England by Major BLAGRAVE in 1813. The _Bacchic Mask_ (No. 35, in the second volume of the _Specimens_) was found, in the year 1674, near Nimeguen, in a stone coffin. It was preserved by the Jesuits of Lyons, in their Collegiate Museum, until their dissolution. From them it passed into the possession of Mr. Roger WILBRAHAM, from whom Mr. KNIGHT obtained it.
