Maurits Cornelis ESCHER (1898-1972). Flat worms, 1959. Lithograph monogrammed MCE and dated 1959 in the plate, signed and numbered n°48/53 II in pencil in the margin. Subject size: Height : 33.2 cm - Width : 41 cm Note: M. C. Escher is a Dutch artist known for his highly graphic lithographs and black engravings. His trips to Italy and the Alhambra were decisive in the graphic aspect of his work, as was his meeting and friendship with the British mathematician Roger Penrose. In "Flat worms", we find the important influence of mathematics and the artist's fascination with complex, impossible objects such as the Necker cube or the Penrose triangle.
