Note 760 — COMUS.
Reading edition
-1. I hate when Vice brings forward refined arguments, and Virtue allows them to pass unchallenged. bolt = to sift or separate, as the boulting-mill separates the meal from the bran; in this sense the word (also spelt boult) is used by Chaucer, Spenser (F. Q. ii. 4. 24), Shakespeare (Cor. iii. 1. 322, Wint. Tale, iv. 4. 375, “the fanned snow that’s bolted By the northern blasts twice o’er,” etc.). The spelling bolt has confused the word with ‘bolt,’ to shoot or start out. See Index to Globe Shakespeare.
