In the Ugaritic texts, El is called a “bull”:
tr
I’l ‘abh I’l mlk dyknnh (“Bull El his father, El the king who
establishes him”)
For
examples of this, see KTU 1.3:v.35-36; 1:4:i.4-6; iv.47-48.
On the importance of this, see the relevant slides here, showing that the Golden Calf in Exodus, and later, the Golden Calves of Jeroboam's temple, were not pedestals, but animal representations of deity.
