Dimness or obnubilation of sight.

A veiling with or concealment in clouds.

Homer, the father of the Poets, by these obnubilations, frequently rescues his heroes from the most imminent danger. Thus, in the third book of The Iliad, when Paris, defeated by Menelaus, is on the point of losing his life, Venus snatches him away in a fog: — // “Then, as once more he lifts the deadly dart, // In thirst of vengeance, at his rival’s heart, // The Queen of Love her fav’rite champion shrouds // (For Gods can all things) in a veil of clouds.”

Something that obscures or causes confoundment; an obfuscation.
