Horse and Shadow I is part of a body of two-dimensional works Antonio Mak began in the 1960s, which is comprised of ink and graphite drawings, mixed-media collages, and etchings. These are distinct from his better-known sculptural practice. Featuring motifs of horses, trees, books, ladders, steps, and chairs, these works are often inspired by the art and theories of Marcel Duchamp and by M. C. Escher’s fantastical perspectives and tessellations. Deceptively simple and sometimes nonsensical, Mak’s arrangements of figures, objects, and animals use visual puns and unusual juxtapositions to probe existential questions. Horse and Shadow I is one of several ink and watercolour drawings by Mak that depicts two horses—one black and one white—standing side by side, facing opposite directions, and separated by a white fence. The white horse’s shadow on the fence aligns with the black horse’s body, connecting the two figures in a strange illusion.
