This has been discussed earlier in the forum. However, as there are still Oera Linda researchers (i.c. German Harm Menkens*) who think that the authenticity of the texts can be established simply by the fact that there was indeed a cataclysm ca. 2200 BCE, here is once more a Frisian Almanac page (1836) that has the same year for the (Biblical) deluge.
* "Die Oera-Linda-Handschriften ~ Die Frühgeschichte Europas" (2013, Lühe-Verlag) and "Der Kampf um die Echtheid der Oera-Linda-Handschriften von 1850 bis heute" (Vortrag 13. September 2015; published by Lühe-Verlag)
|page 12 from "Friesche Volks-almanak" 1836 (source)|
Two relevant lines translated:
The year of our Christian era . . . 1836
Since the deluge . . . 4029
4029 -/- 1836 = 2193
Flood year in OLB (page 00a, letter Hidde): 3449 -/- 1256 = 2193
As my readers know, I rather advocate OLB's authenticity than any hoax theory. However, the flood year on itself is not good evidence (for either theory), since it was known even before Cornelis Over de Linden got the manuscript in his possession (1848 according to himself).
