"...Sir that is France, a faire beseeming friend,
On yonder continent stands Ireland,
On this side Brittaine, and on that side Garsie,
Ilands besides of much hostillitie,
Which are as sun-shine, sometimes splendious,
Anon disposed to altering frailtie.
We that all neighbor must so strēgth our being,
As fearelesse we may frolicke yet not seeing...."
