Eric Gill's types include:  These dates are somewhat debatable, since a lengthy period could pass between Gill creating a design and it being finalised by the Monotype drawing office team (who would work out many details such as spacing) and cut into metal. In addition, some designs such as Joanna were released to fine printing use long before they became widely available from Monotype. The family Gill Facia was created by Colin Banks as an emulation of Gill's stone carving designs, with separate styles for smaller and larger text. One of the most widely used British typefaces, Gill Sans, was used in the classic design system of Penguin Books and by the London and North Eastern Railway and later British Railways, with many additional styles created by Monotype both during and after Gill's lifetime. In the 1990s, the BBC adopted Gill Sans for its wordmark and many of its on-screen television graphics. Gill was commissioned to develop a typeface with the number of allographs limited to what could be used on Monotype or Linotype machines. The typeface was loosely based on the Arabic Naskh style but was considered unacceptably far from the norms of Arabic script. It was rejected and never cut into type. Gill published numerous essays on the relationship between art and religion, and a number of erotic engravings. Some of Gill's published writings include:  Gill also provided woodcuts and illustrations for a range of other books. As a young man, Gill was a member of the Fabian Society, but later resigned. In the 1930s Gill became a supporter of social credit; later he moved towards a socialist position. In 1934, Gill contributed art to an exhibition mounted by the left-wing Artists' International Association, and defended the exhibition against accusations in "The Catholic Herald" that its art was "anti-Christian". Gill was adamantly opposed to fascism, and was one of the few Catholics in Britain to openly support the Spanish Republicans. Gill became a pacifist and helped set up the Catholic peace organisation Pax with E. I. Watkin and Donald Attwater. Later Gill joined the Peace Pledge Union and supported the British branch of the Fellowship of Reconciliation. In 1904, Gill married Ethel Hester Moore (1878–1961), with whom he had three daughters and an adopted son. In 1907, he moved with his family to "Sopers", a house in the village of Ditchling in Sussex, which would later become the centre of an artists' community inspired by Gill.
