In the podcast of 23-2-2015 (at 24:00 min.), about Domitian and the Book of Revelation, the question is raised if the concept of "the first and the last", or alpha & omega in the context of a godhead existed in earlier religions or traditions. The Oera Linda Book (OLB) has this fragment in its Wralda 'theology': "Out of Wralda both the beginning and the end come. All things merge into him." FONUT WR.ALDA KVMTH.T.ANFANG ÀNDET ENDE ALRA THINGA GÉITH IN IM VPPA. (p.98 of original manuscript with my new translation and transliteration). The OLB is a collection of Old Frisian texts which seems to be a 13th century copy of much older originals, initially compiled in the ca. 600 BCE in what is now the Netherlands. For more about its authenticity question see the one hour video on Youtube 'oeralinda' channel ("Saved from the Flood"), or listen to Red Ice interviews of 2016/2018.
