Where did the aphorism 'three can keep a secret if two of them are dead' originate?

Benjamin Franklin, in "Poor Richard's Almanac" and it means that you can trust no one but your self with your own secret...so tell nobody

In volume four of The history of the life and times of Cardinal Wolsey Prime Minister to King Henry VIII by George Cavendish, published by Joseph Grove in 1744, King Henry VIII is quoted as saying essentially the same thing:

"three can keep Counsel if two be away ; and, if I knew my Cap was privy to my Counsel, I would cast it into the Fire, and burn it"

Since Henry predates Franklin by at least a couple hundred years, the attribution to him indicates that the saying was current long before Ben was born. Even the mention of this saying in a book published in 1744 casts doubt on it being original to Franklin.
