Gray Face - Poetry & It's meaning

Over the hills, I see a face of grey.

Hooves like donkeys, but it didn't bray.

Over the meadows, I see the other day.

The collossus of a bod, eating my sheeps away.

I may had felt like fear and I may had runaway.

But I read a word or two and the devil vanished away.

I wrote this when I was 17 or something. I have always liked supernatural, paranormal and demon related things. Djinns are interesting. So I came up with this. 

It talks about a shepherd seeing a cattle-like creature but it belongs to the demon or Djinn's realm. Like, it's a sheep-like creature, but it has red eyes and horns and it resembles a cross Ox and Yak. I read somewhere (many, many years ago. Online.) That it behaves and works similar to beasts of burden of humans. But this creature is a beast of burden for Djinns. 

The shepherd one morning sees this demonic cattle devouring one of it's sheep. It was a huge creature, with a huge body and grey face. It struck fear in the shepherd's heart and felt like running away. But instead he said a few words of God, asking God to help him and remove this beast and so the devil vanished, defeated. 

That's the story I thought behind this one.
