Cockaigne

An old French poem on the Land of Cockaigne described it as an ideal land of luxury and ease.

Never comes the trader thither, never o'er the purple main Sounds the oath of British commerce, or the accents of Cockaigne.

Hence our own word of "Cockaigne," about the derivation of which so many contradictory guesses have been made.

It is, says Dixon, the common English broadsheet "turned into the dialect of Cockaigne."
