The fictional planet visited in C.S. Lewis’s Perelandra is called Perelandra.
Published in 1943, Perelandra is the second novel in Lewis’s Space Trilogy. Its protagonist, Elwin Ransom, travels from Earth to the planet Perelandra, which is also identified with Venus. There he encounters a newly created world and becomes involved in a spiritual and moral struggle surrounding its inhabitants.
The trilogy’s planetary names can be confusing. Malacandra is Mars, the destination in the first novel, Out of the Silent Planet. Thulcandra is Earth, described as the silent planet because it is cut off from wider cosmic communication. Perelandra differs from conventional space adventure because its central conflict concerns temptation, freedom, innocence, and the possibility of a second fall. Lewis combined science-fiction settings with Christian theological themes throughout the trilogy.
