Plot of ground where herbs, fruits, flowers, vegetables, or trees are cultivated. The earliest surviving detailed garden plan is Egyptian and dates from about 1400 BC; it shows tree-lined avenues and rectangular ponds. Mesopotamian gardens were places where shade and cool water could be enjoyed; Hellenistic gardens were conspicuously luxurious in their display of precious materials, a tradition carried over by Byzantine gardens. Islamic gardens made use of water, often in pools and fed by narrow canals resembling irrigation channels. In Renaissance Europe, gardens reflected confidence in human ability to impose order on the external world; Italian gardens emphasized the unity of house and garden. French 17th-century gardens were rigidly symmetrical, and French cultural dominance in Europe popularized this style into the next century. In 18th-century England, increasing awareness of the natural world led to the development of natural gardens that made use of irregular, nonsymmetrical layouts. Chinese gardens have generally harmonized with the natural landscape, and have employed rocks gathered from great distances as a universal decorative feature. Early Japanese gardens imitated Chinese principles; later developments were the abstract garden, which might feature only sand and rocks, and miniature gardens made in trays (seebonsai).
