Magritte's earliest paintings, which date from about 1915, were Impressionistic in style. From 1916 to 1918, he studied at the Académie Royale des Beaux-Arts in Brussels. He studied under Constant Montald. The paintings he made in the years 1918–1924 were influenced by Futurism and by the offshoot of Cubism practiced by Metzinger. Most of his works of this period are female nudes.
