This I see ye visibly, and now believeThat he, the Supreme Good, t’whom all things illAre but as slavish officers of vengeance,Would send a glistering guardian, if need were,To keep my life and honour unassailed.Was I deceived, or did a sable cloudTurn forth her silver lining on the night?I did not err. there does a sable cloudTurn forth her silver lining in the night,And cast a gleam over this tuited grove;I cannot halloo to my brother, butSuch noise as I can make to be heard farthestI’ll venture; for my new-enlivened spiritsPrompt me, and they perhaps are not far offShe begins to sing-“Sweet Echo sweetest Nymph, that liv’st unseen with thy aery shell” ~ Milton’s Comus, Scene I
