the move to realism were Esaias van de Velde (1587–1630) and Hendrick Avercamp (1585–1634), both also mentioned above as genre painters – in Avercamp's case the same paintings deserve mention in each category. From the late 1620s the "tonal phase" of landscape painting started, as artists softened or blurred their outlines, and concentrated on an atmospheric effect, with great prominence given to the sky, and human figures usually either absent or small and distant. Compositions based on a diagonal across the picture space became popular, and water often featured. The leading artists were Jan van Goyen (1596–1656), Salomon van Ruysdael (1602–1670), Pieter de Molyn (1595–1661), and in marine painting Simon de Vlieger (1601–1653), with a host of minor figures – a recent study lists over 75 artists who worked in van Goyen's manner for at least a period, including Cuyp. From the 1650s the "classical phase" began, retaining the atmospheric quality, but with more expressive compositions and stronger contrasts of light and colour. Compositions are often anchored by a single "heroic tree", windmill or tower, or ship in marine works. The leading artist was Jacob van Ruisdael (1628–1682), who produced a great quantity and variety of work, using every typical Dutch subject except the Italianate landscape (below); instead he produced "Nordic" landscapes of dark and dramatic mountain pine forests with rushing torrents and waterfalls. His pupil was Meindert Hobbema (1638–1709), best known for his atypical Avenue at Middelharnis (1689, London), a departure from his usual scenes of watermills and roads through woods. Two other artists with more personal styles, whose best work included larger pictures (up to a metre or more across), were Aelbert Cuyp (1620–1691) and Philips Koninck (1619–1688). Cuyp took golden Italian light and used it in evening scenes with a group of figures in the foreground and behind them a river and wide landscape. Koninck's best works are panoramic views, as from a hill, over wide flat farmlands, with a huge sky. A different type of landscape, produced throughout the tonal and classical phases, was the romantic Italianate landscape, typically in more mountainous settings than are found in the Netherlands, with golden light, and sometimes picturesque Mediterranean staffage and ruins. Not all the artists who specialized in these had visited Italy. Jan Both (d. 1652), who had been to Rome and worked with Claude Lorrain, was a leading developer of the subgenre, which influenced the work of
