684. _sereyns_, i. e. Sirens. Cotgrave has: '_Sereine_, f. a Mermaid.'
Chaucer takes no notice of G. de Lorris' notable etymology, by which he
derives _Seraines_ from the adj. _seri_. Cotgrave gives (marked as
obsolete): '_Seri_, m. _ie_, f. Quiet, mild, calm, still; fair, clear.'
693. _wel bigo_, the opposite of 'woe begone'; as in l. 580. Cf. 'glad and
wel begoon'; Parl. Foules, 171.
