Nature worship describes a variety of religious, spiritual and devotional practices that focus on natural phenomenon. A nature deity can be in charge of nature, the biosphere, the cosmos or the universe. Nature worship can be found in panentheism, pantheism, deism, polytheism, animism, totemism, shamanism and paganism where deities are viewed as the embodiment of natural forces. Common to most forms of nature worship is a spiritual focus on the individual's connection to the natural world and reverence towards it.

Kenneth McKenzie Clark, Baron Clark, OM, CH, KCB, FBA (13 July 1903 – 21 May 1983) was a British author, museum director, broadcaster, and one of the best-known art historians of his generation. In 1969, he achieved an international popular presence as the writer, producer, and presenter of the BBC Television series, Civilisation.

Clark was born in London, the only child of Kenneth MacKenzie Clark and Margaret Alice McArthur. The Clarks were a wealthy Scottish family with roots in the textile trade (the "Clark" in Coats & Clark threading). His great-great-grandfather had invented the cotton spool. Kenneth Clark the elder had retired in 1909 at the age of 41 to become a member of the 'idle rich' (as described by W. D. Rubinstein in The Biographical Dictionary of Life Peers).

Clark was educated at Winchester College and Trinity College, Oxford, where he studied the history of art. In 1927 he married a fellow Oxford student, Elizabeth Jane Martin, who was Irish. The couple had three children: Alan, in 1928, and twins Colette (known as Celly) and Colin in 1932.
