stream mentally and move in either direction, although this is a dangerous venture, for they may be carried away erratically by the stream. ... In San Francisco nine associates, who have been troubled by occasional memories of [the planet] Eos, band together to explore the time stream. They live out crisis moments in both times. Another mid-century novel which employed the term in its title was The Ship That Sailed the Time Stream (1965) by G. C. Edmondson (pseudonym of José Mario Garry Ordoñez Edmondson y Cotton). John Clute writes that this "and its sequel, To Sail the Century Sea (1981), are amusingly and graphically told Fantastic-Voyage tales involving a US ship and its inadvertent Time Travels. They remain his most successful books." Other fiction titles with the term include J. Robert King's 1999 novel Time Streams (), Michael Moorcock's 1993 collection A Nomad of the Time Streams (), and Charles M. Saplak's short story "Backwater by the Time Stream" (Manifest Destiny #1, Winter 1993). Discussing the theme of parallel universes, in an encyclopedia article which can usefully be applied to the concept of timestreams, Brian Stableford and David Langford write, "A parallel world is another universe situated 'alongside' our own, displaced from it along a spatial fourth Dimension (parallel worlds are often referred to in sf as 'other dimensions'). Although whole universes may lie parallel in this sense, most stories focus on parallel Earths. The parallel-world idea forms a useful framework for the notion of Alternate History, and is often used in this way... The idea that other worlds lie parallel to our own and occasionally connect with it is one of the oldest speculative ideas in literature and legend; examples range from Fairyland to the 'astral plane' of Spiritualists and mystics. There are two basic folkloristic themes connected with the notion; in one, an ordinary human is translocated into a fantasy land where s/he undergoes adventures and may find the love and fulfilment that remain beyond reach on Earth; in the other, a communication or visitation from the other world affects the life of an individual within this world, often injuring or destroying that person. Both patterns are very evident in modern imaginative fiction, shaping whole subgenres... A common variant of the theme is that of a multiplicity of almost-identical worlds existing in parallel: alternate worlds in which there has been no significant change." Fantasy fiction Rick Sutcliffe
