Originally presented by Galeria Zé dos Bois in Azores and Lisbon, Lua Cão is the result of more than a decade and a half of conversation between Checa, Estrela, and Gusmão and Paiva. The title refers to a rare optical phenomenon where the moon’s light is refracted to appear in a halo with a pair of adjacent ‘moon dogs’. Moons, eyeballs, multiple exposures, tunnels, light rays, and atmospheric and optical illusions proliferate throughout the exhibition to emphasize the role the mechanics of vision plays in both artistic practices, and to demonstrate their shared interest in the moving image that consistently connects abstractions to illusions, the everyday to the impossible.
