translation and origin of a quote

[LSL13]

Can someone tell me where this is from and what it means?  Many thanks!


Thanne longen folk to goon on pilgrimages
And palmeres for to seken straunge strondes
To ferne hawles, kowthe in sondry londes;

[Beloved Warrior]

Geoffrey Chaucer, Canterbury Tales, General Prologue, Lines 12-14

"Then folk do long to go on pilgrimage,
 And palmers to go seeking out strange strands,
 To distant shrines well known in distant lands."
