Credit and rights

Retold by PlayOwl from Twenty Thousand Leagues Under the Sea by Jules Verne (1870). Source: Twenty Thousand Leagues Under the Sea by Jules Verne (1870).

Adaptation
Follows the events of the opening of Twenty Thousand Leagues Under the Sea (Vingt mille lieues sous les mers) by Jules Verne, a French novel. The story is shortened and retold in new sentences. No translation, abridgement, film or illustrated edition was copied: the text was checked against the English translations by Lewis Mercier (1872) and F. P. Walter (1999) and reworded so that no sentence follows them. Only the events, the characters, the Latin motto "Mobilis in Mobili" and a few figures come from the original. Public domain. In the United States, copyright in works published before 1929 has expired, and this work was first published in 1869 and 1870. In countries where copyright lasts for the author's life plus 70 years, the term ended on 31 December 1975, because Jules Verne died in 1905. The retelling uses the wording of no English translation (it was checked against Mercier's and Walter's), so no translator's rights are involved. PlayOwl claims no rights in the underlying story.
