Perceptismo : teórico y polémico
"Raúl Lozza was the founder of 'Perceptism', which proclaimed the idea of the unity of form and colour. The movement's journal "Perceptismo" became the platform for Lozza's art-theoretical stance, and the movement's geometric works, and their relationship to the history of modern art."--AbeBooks, description of first issue, viewed online June 20, 2017
