The Aspid Serpent

A Serpent, which that Aspidis
Is cleped, of his kynde hath this,
That he the Ston noblest of alle,
The which that men Carbuncle calle,
Berth in his hed above on heihte.
For which whan that a man be sleyhte,
The Ston to winne and him to daunte,
With his carecte him wolde enchaunte,
Anon as he perceiveth that,
He leith doun his on Ere al plat
Unto the ground, and halt it faste,
And ek that other Ere als faste
He stoppeth with his tail so sore,
That he the wordes lasse or more
Of his enchantement ne hiereth;
And in this wise himself he skiereth,
So that he hath the wordes weyved
And thurgh his Ere is noght deceived.
