«These days, Jessurun de Mesquita (1868-1944) is known principally for his association with one of his pupils, M.C. Escher. He is also well-known in the Netherlands for his crisp woodcuts of animals in Amsterdam’s Artis zoo. But De Mesquita’s surviving oeuvre is far more varied and innovative than is generally assumed. This first major retrospective in twenty years illustrates the point with drawings, water colours, woodcuts, etchings, paintings and examples of the applied arts.
«With Nazi Germany’s invasion of the Netherlands in May, 1940, de Mesquita, already in poor health, was forced to lead a secluded life, limiting his work largely to sketches. In the winter of 1944, on either January 31 or February 1, the occupying German forces entered the home of the de Mesquita family in Watergraafsmeer, now part of Amsterdam, and apprehended him, his wife Elisabeth, and their only son Jaap. Transported to Auschwitz, Samuel Jessurun and Elisabeth were sent to the gas chambers within days of their arrival on February 11; Jaap perished in the concentration camp at Theresienstadt on March 20. Escher and some of Jaap’s friends were successful in rescuing some of the works that had remained in the de Mesquita home.» Samuel Jessurun de Mesquita (Wikipedia)

Reli a lista. Reli-a em voz alta, pausada. Não podia ser, era uma coisa que não podia ser e, no entanto, ali estava, sólida e absurda, como os famosos Mundos Impossíveis, desenhados por M. C. Escher: escadarias que ascendem e descendem ao mesmo tempo, cubos com as arestas cruzadas, água que desce através de um canal, num estranho edifício, até cair, em cascata, em direcção ao mesmo ponto, lá em baixo, ou lá em cima, de onde havia partido.
Que lindo, filha. Parece-me um milagre.
