Artwork of the Day - what IS it!?

So what is this? A contemporary piece? Looks a bit like a Hirst  life size bull made in metal!?  

So it looks like it could be silver (correct) but is that gold on the brow of the beast? (it is!)

So it could be a Damien Hirst maybe!? (nope!)

🤔

ANSWER:

Life-size Silver Bull found in a sacred pit near the Stoa of the Athenians. It was made out of silver sheets with some body parts made out of gold. 

Dates to the middle of the 6th Century BC.
