Given the ubiquity of the work of M.C. Escher (1898–1972), it’s hard to believe that the current show M.C. Escher: Infinite Dimensions at the Museum of Fine Arts is the first time original prints by the iconic Dutch artist and designer have been displayed in Boston. Now fans can enjoy 50 of his dazzling and delightfully confounding images mixing complex, mathematical precision and impossible perspectives with a playful imagination, including the 13-foot-long Metamorphosis II (1939–40) that combines the shapes of various insects, animals and geometric shapes in a puzzle-like, interlocking pattern. For further insight into Escher’s continuing appeal, a lecture by curator Ronni Baer takes place April 5 from 6:30–7:30 p.m. at the MFA’s Remis Auditorium.
