On the philosophy of painting: a theoretical and practical treatise..
A theoretical and practical treatise on painting by Henry Twining, published in London by Longman, Brown, Green, and Longmans in 1849 for students and amateur artists learning perspective, light and colour. Line engravings pair bare geometric diagrams — projection planes, sight lines, vaulted arches, a room with framed pictures — with sketched village roofs, boats reflected in water and oak foliage.
