This woodcut print by M.C. Escher, titled 'Porthole', depicts a ship seen through a circular window. The intricate cross-hatching and the inclusion of a curtain create a sense of depth and texture.

M.C. Escher (1898-1972) was a Dutch graphic artist known for his mathematically inspired woodcuts, lithographs, and mezzotints. His work often features impossible constructions, explorations of infinity, and tessellations. Escher's art appeals to a wide audience, blending artistic skill with mathematical concepts. He gained popularity in the mid-20th century, particularly among scientists and mathematicians, and his prints remain highly sought after. 'Porthole', created in 1930, is a woodcut print. The image depicts a ship viewed through a porthole. The composition is divided into distinct areas, with the ship in the centre, framed by the circular window. The surrounding area is filled with a dense, cross-hatched pattern, creating a textured effect. A curtain hangs to the right, adding depth and contrast to the scene. The overall effect is one of looking out from within a confined space, offering a glimpse of the open sea.
