The zodiacal sign Taurus was not based on your normal everyday bull.
The model for Taurus was the extinct reem. Reem comes from a verb meaning to rise or to be lifted up. In other words, it was named for its ascendency over other creatures. Larger than today's cattle, its horns were doubly curved. It was extremely strong, and—more importantly—it was wild.
The reem may have had horns as big as the ones in this photo, but it would never have had a cord hanging from its neck. God asked Job: "Will the reem be willing to serve you?" Job 29:9-12.
The untamed reem is a fitting model for this star sign that represents the Lord. "He's not a tame lion," as C. S. Lewis says in The Chronicles of Narnia. God is to be feared, not put in a rocking chair or dressed in a Santa suit.
The reem represents God's power over his enemies. "For behold, your enemies, O LORD, for behold, your enemies shall perish; all evildoers shall be scattered . . . you have exalted my horn like that of the wild ox." (Psalm 92:9-10).
