Azazel is described as a dragon and also as a goat-like demon in the 'Apocalypse of Abraham.'
The Apocalypse of Abraham is a pseudepigraphic work (a text whose claimed authorship is unfounded) based on the Old Testament.
Probably composed between about 70–150 AD, it is of Jewish origin and is usually considered to be part of the Apocalyptic literature.
It has survived only in Old Slavonic recensions — it is not regarded as authoritative scripture by Jews or any Christian group.
French occultist Collin de Plancy's 'Dictionnaire Infernal' (1818) described Azazel as the guardian of goats.
He is also sometimes depicted as a demon like creature holding, or riding a goat.
