Errantry

I am a knight, my bearings a dragon
proper (indeed) on barry wavy field,
a sign that land or sea I do not yield.
Still I'm happier with leather flagon
(not being the sort who'd go on the waggon),
that sort of weapon's easier to wield
but none would dare to limn it upon shield,
but truly all my fortune comes from lagan.
Now, tellers of romances all agree
that dragons far from eating ladies fair
are gentle creatures, always kind and sweet;
an awful state, this one that's come to be,
when dragons fly unhindered through the air,
and never knight and monster come to meet.
