The House of Arden
The House of Arden is a novel for children written by the English author E. Nesbit and published in 1908.The past events they witness include The final episode, in which the children rescue their father from a lost civilization in South America, is reminiscent of the legends of El Dorado and other Cities of Gold.A sequel, Harding's Luck, was published in 1909, in which the nominally Tudor character of "cousin Richard Arden", who acts somewhat mysteriously in the original book, including recognising a Kodak camera, is given something of a backstory.J. R. R. Tolkien's unpublished attempt at a time travel novel, The Lost Road functions in the same way.The Lost Road has father/son pairs named Edwin/Elwin, Eadwine/Aelfwine, Audoin/Alboin, Amandil/Elendil (all meaning "Bliss-friend/Elf-friend" in Old English, Old High German, and Lombardic).
