Who was the original person to say "ignorance is bliss?"?

Question

Just need the person so I can say who it was in a paper i am writing....

Answer 1

According to Bartlett's Familiar Quotations:

"Where ignorance is bliss,

’T is folly to be wise."

From "Eton College.  Stanza 10"  by Thomas Gray

Answer 2

I think a guy named Bob Miller, circa 273 C.E.

Answer 3

The original speaker!? Well, I think the oldest expression of those words come from the cyclops in ancient Greek mythology after they traded one eye for the ability to see the future, but the only future they got to see was how they would die.

I'm sorry, but I don't remember who wrote it...my mythologies class was too many years ago.
