Sylvani Merilion (née Smith) (4 October 1936 - 31 March 2019) was an English artist and former art teacher. In 1964 she was one of the four founder members of Birmingham's Ikon Gallery. Merilion's artworks in the 1960s featured images of astronauts and space travel, influenced by pop art and the visual forms of the Bauhaus. The Guardian said of them in 2004 - "Her drawings of astronauts aren't strident or overdetermined, like most Pop works, just bright, clever and clear."
