This generously illustrated book examines the most significant period in the work of Lawren Harris, who was central to defining a distinctive Canadian art in the 20th century. Sparse landscapes of Lake Superior s northern shores, bold visions of the Rocky Mountains and haunting landscapes from the Eastern Arctic are hallmark themes of Lawren Harris s paintings. He was a founding member of the renowned Group of Seven artists group, who believed that the Canadian landscape was central to the foundation of a national identity. Focusing on Harris s most important work of the 1920s through the early 1930s, this monograph features a selection of major works that are as iconic in Canada as those of Georgia O Keeffe and Edward Hopper in the U.S. His remarkable use of colour, light and composition resulted in powerful scenes that reflect his progress toward a universal vision of nature s spiritual power. Drawn from the Art Gallery of Ontario s substantial holdings as well as other public collections throughout Canada, this publication repositions Harris s work and establishes him as a major figure within the wider context of 20th-century modern painting in the Americas. Published in association with the Hammer Museum, Los Angeles and the Art Gallery of Ontario, Toronto.
