In the mythological writings of William Blake, '''Thiriel''' is the first son of Urizen. There is a possible confusion with ''Tiriel'', the protagonist of the first prophetic book, of that name.
In ''The Book of Urizen'', Thiriel has an explicit identification of his place as Air in the Four Elements, matched to Urizen's four sons.<ref name="Damon">{{cite book |last1=Damon |first1=Samuel Foster |title=A Blake Dictionary: The Ideas and Symbols of William Blake |date=1988 |publisher=UPNE |isbn=9780874514360 |page=403 |language=en}}</ref> His birth is described in Chapter VIII:
:Most Urizen sicken'd to see :His eternal creations appear, :Sons and daughters of sorrow, on mountains, :Weeping, wailing. First '''Thiriel''' appear'd, :Astonish'd at his own existence, :Like a man from a cloud born
Thiriel appears also in ''The Four Zoas'', where he becomes Palamabron.<ref name="Damon"/> At the end of the Seventh Night, we read: :Urizen became Rintrah Thiriel became Palamabron
