Bull of Heaven

Okay, so you know how there are some stories about really big and powerful animals, like elephants or lions? Well, in some ancient stories, there is a creature called the Bull of Heaven. It's supposed to be a massive bull that is so strong, it can cause earthquakes just by stomping its hooves.

In some stories, people would offer sacrifices to the Bull of Heaven to make sure it didn't get mad and destroy everything around it. In other stories, brave heroes would try to fight the Bull of Heaven to prove their strength and bravery. Either way, the Bull of Heaven was a big deal in these stories because it was thought to have incredible power and strength.

Today, people sometimes use the phrase "Bull of Heaven" to describe something or someone that is very powerful or impressive. It's kind of like saying "that thing is as strong as a bull!"
