"Thet Oera Linda Bok, Naar een Handschrift uit de Dertiende Eeuw" by J. G. Ottema is a manuscript in pseudo-runic script brought forward in 1867. Presented as an ancient Frisian chronicle, it claims a 4,000-year-old civilization and traces European peoples to Frisian origins through three ancestral mothers. The work depicts conflicts between free Frisians and eastern peoples, weaving legendary figures like Wodin and Odysseus into an alternate history. Long considered a forgery, it's now viewed as mystification or parody.
