M. Dupré.--His Drawings in Greece.--L'Eglise des Carmes.--M. Vinchon's Picture of the National Convention.--Léopold Robert's Fishermen.--Reported cause of his Suicide.--Roman Catholic Religion.--Mr. Daniel O'Connell. We went the other morning, with Miss C----, a very agreeable countrywoman, who has however passed the greater portion of her life in Paris, to visit the house and atelier of M. Dupré, a young artist who seems to have devoted himself to the study of Greece. Her princes, her peasants, her heavy-eyed beauties, and the bright sky that glows above them,--all the material of her domestic life, and all the picturesque accompaniments of her classic reminiscences, are brought home by this gentleman in a series of spirited and highly-finished drawings, which give decidedly the most lively idea of the country that I have seen produced. Engravings or lithographs from them are, I believe, intended to illustrate a splendid work on this interesting country which is about to be published. In our way from M. Dupré's house, in which was this collection of Greek drawings, to his atelier--where he was kind enough to show us a large picture recently commenced--we entered that fatal "Eglise des Carmes," where the most hideous massacre of the first revolution took place. A large tree that stands beside it is pointed out as having been sought as a shelter--alas! how vainly!--by the unhappy priests, who were shot, sabred, and dragged from its branches by dozens. A thousand terrible recollections are suggested by the interior of the building, aided by the popular traditions attached to it, unequalled in atrocity even in the history of that time of horror. Another scene relating to the same period, which, though inferior to the massacre of the priests in multiplied barbarity, was of sufficient horror to freeze the blood of any but a republican, has, strange to say, been made, since the revolution of 1830, the subject of an enormous picture by M. Vinchon, and at the present moment makes part of the exhibition at the Louvre.
