b France, 1576; bur Paris, 28 Feb 1626,He was a Huguenot from the Dieppe region (Normandy). Between c. 1595 and 1598 he visited Italy, where he was strongly influenced by the gardens laid out c. 1570 by Bernardo Buontalenti at Pratolino, near Florence, and by their mechanical artifices. De Caus's work also reveals a knowledge of the gardens of the Villa d'Este in Tivoli. From c. 1598 to 1610 he was in Brussels, in the service of the Stadholder of the Netherlands, Albert, Archduke of Austria. There he was the engineer responsible for wells, fountains and the automatic works in the two grottoes (destr. 1768) in the garden of the Stadholder's residence. From 1610 he lived in England, moving in the artistic circle of Henry, Prince of Wales, to whom he taught drawing and for whom he built a picture gallery at Richmond. Together with Constantino de' Servi (1554-1622) he was engineer and supervisor of the waterworks at Richmond Palace. De Caus dedicated his first book, La Perspective (1612), to Prince Henry and included garden designs for the Prince in his second book, Les Raisons des forces movvantes (1615). He worked at several sites in England, including Somerset House in London, where he is thought to have erected a Parnassus, and at Greenwich Palace, Hatfield House and Gorhambury House (Herts) and Wilton House (Wilts). Nothing has survived of his work of this period.
