_The Lybelle of Englyshe Polycye_, in _Political Poems and Songs_, ed.Thos.Wright (Rolls Ser., 1861), II, p.162.This remarkable poem was written in 1436 or 1437, in order to exhort the English 'to kepe the see enviroun and namelye the narowe see' between Dover and Calais, since in the author's opinion the basis of England's greatness lay in her trade, for the preservation of which she needed the dominion of the seas.

Its chief value lies in the very complete picture which it gives of English import and export trade with the various European countries.
There is a convenient edition of it in _The Principal Navigations Voyages Traffiques and Discoveries of the English Nation by Richard Hakluyt_ (Everyman's Lib.
