The wrinkles under the eyes, or from the outward corners of the eyes, which are the effect of age, and which are thought to resemble the impression of the feet of crows.--Todd.
So long mote ye liven, and all proud,
Till crowes feet growin under your eie,
And send you then a mirrour in to prie.
Chaucer, Troil. and Cres.
And by myne eye the crow his claw doth wright.
Spenser, Shepherd's Cal. Dec.
