Hint: see his sonnet on his second wife Catherine, specifically the line--"...vested all in white--"
(sonnet #MMMMMMMDCCXVII)
Snow. Was last summer traipsing through a tale Of mirey puddles? Ah. Tis wet fr'intents, But with frore air presiding all's white hence Or icy, like the curving claws that hail From silent eaves, no scimiter--in pale Excuse for fancied heights--but fringing thence The void twixt roof and far below, a sense Perchance of grasping in their scope's detail. I look out half surprised all's buried fer The umpteenth time, as flakes cavort now through Unnumbered hours likeas soft mists in tour, Sip that espresso foamed milk crowns anew In thoughtful silence, not unlike that pure Calm listning as snow falls in silence too.

"...all in white---" has such a sanctified sense, doesn't it? I've wisht countless times to amend the text notes on that reference since even David M. Mains failed to realize whence Milton culled that idea.
