A selection of illustrations from Variae Architecturae Formae, a series of architectural studies after the works of Joanne Vredemanni Vriesio, also known in Dutch as Hans Vredeman de Vries (1527–c.1607). De Vries was a Dutch Renaissance architect, painter, and engineer. Studying Vitruvius and Sebastiano Serlio, (translated by his teacher Pieter Coecke van Aelst), he became an internationally known specialist in perspective and, as well as books on architecture, perspective and garden design, he became the city architect and fortification engineer for the city of Antwerp. The etchers of the images in the book are given as Jan and Lucas Van Doetecum, two brothers from Hollstein.(Wikipedia)
