Interesting scientific book complete with all illustrations and antique binding in excellent condition.

Sébastien LECLERC's style of illustration strongly influenced the 18th-century French vignettists, prefiguring the grace and elegance of the best French rococo. LECLERC (1637-1714), a native of Lorraine, adapted the technique of his countryman Jacques Callot (1592-1635). Professor of geometry and perspective at the Royal Academy of Arts and Sciences, LECLERC also worked for Louis XIV as "Graveur du Roi." Lovely copy, of this uncommon and influential book, a popular manual for artists and architects of the 17th century.

He specialized in subtle reproductive drawings, etchings, and engravings of paintings; and worked mostly in Paris, where he was counseled by the King's painter, Charles Le Brun, to devote himself entirely to engraving. Leclerc joined the Académie Royale de Peinture et de Sculpture in 1672 and taught perspective there. He worked for Louis XIV, being made "graveur du Roi" (attached to the Cabinet du Roi), doing engraving work for the royal house. Leclerc also engaged in periodic work as a technical draftsman and military engineer. Shipping: via UPS, DHL, National Postal Services, protected, INSURED and fully tracked package.
