The Book of Giants: The Fallen Angels and their Giant Sons

Ogias the Giant, also known as The Book of Giants, is thought to have been based on the Book of Enoch, a work from the 3rd century BC concerning Nephilim, which are the offspring of fallen angels. The text relates how before the Biblical Flood, a giant named Ogias fought a great dragon [perhaps dinosaur]. A brief mention of this giant "Ohia" is found in the Babylonian Talmud (Nidah, Ch 9) where it is said "Sihon and Og [from the book of Genesis] were brothers, as they were the sons of Ohia the son of Semjâzâ [one of the leaders of the fallen angels in the Book of Enoch]".

This book is one of the books from the New Testament apocrypha which concerned the Old Testament. Aramaic fragments of it, along with other fragments of the Book of Enoch, were found among the Dead Sea Scrolls at Qumran. In the version of the Book of Giants, the book became well travelled, and exists in many languages and cultures. It has sparked intense interest among scholars and laymen alike.
