Quote: In the collection of P. Cloix at Montigny-sur-Loing are two drawings by Mantegna which are plainly preliminary studies for the groups of Mars and Venus, and Mercury and Pegasus in the Parnassus in the Louvre. The drawing of the Mercury and Pegasus is quite superior to the finished group and is another example of Mantegna's curious failure to achieve the effects outlined in his cartoons. (F. SCHMIDT-DEGENER, Gaz. B.-A.XXXVIII, 1907, pp. 285-295.)
