by Jean Leymarie.Rizzoli, $55.00. Corot painted landscapes, portraits, genre pieces, nudes, dancing nymphs, religious scenes, still lifes—only machinery, battles, and storms at sea eluded his interest. Consequently, a book illustrating his work offers a variety of subject matter accompanied by subtle shifts in style. Mr. Leymarie’s text concentrates, helpfully, on the delicate technical changes, which kept Corot so happily occupied that he needed no other adventures. He died at seventy-nine, regretting all the things he had never got around to painting. Illustrations—fifty in color—chronology, bibliography, index. Translated by Stuart Gilbert.
