John Lydgate (1370 - 1450 / Lidgate, Suffolk)

Who clymbeth hyest gothe ofte base,
Ensample in medowes thow mayst se
That nowe is heye some tyme was grase.

Lenvoye.
Go forth anon, thou short dite,
Bydde folke not trust this worlde at all,
Bydde theme remembre on e cite
Which is a-bove celestiall;
Of precious stones bylt is the wall,
Who clymbeth theder gothe nevar base,
Out of that place may be no fall,
Ther is no heye but all fresh grase.
