Leigh and Lomazzo on the Virtue of Colours (Renaissance Colour Symbolism III) brings together relevant extracts from four sources. The first is The Accedens of Armory, published in London in 1562 by Gerard Leigh (c. 1520-63). The second is the Trattato dell'arte della pittura, scoltura, et archittetura, published in Milan in 1584 by Giovanni Paolo Lomazzo (1538-92), parts of which were translated by Richard Haydocke (1570-1642) as A Tracte Containing the Artes of Curious Paintinge, Carvinge and Buildinge, published in Oxford in 1598. Also included is the Trattato de i colori nelle arme, nelle livree, et nelle devise, the Italian translation of Le Blason des couleurs en armes, livrees, et devises, by the Sicily Herald (Jean Courtois) and Gilles Corrozet and published in Paris in 1527.
