"'He doth sail into a Cornish port without a bark.'
It is and Italian Proverb, where it passeth for a description (or derision) of a man as is wronged by his wife's disloyalty. The wit of it consists of an illusion to the word Hora."
[So - not really Cornish - but worth including here I think! I am guessing the Hora bit comes from the italian word for Cornish - I cannot find it online.]
