Vigil

Vigil, tacuinum sanitatis casanatensis (14th century)
A Knight's Vigil by John Pettie

A vigil, from the Latin vigilia meaning 'wakefulness' (Greek: pannychis,[1] παννυχίς or agrypnia[2] ἀγρυπνία),[3] is a period of purposeful sleeplessness, an occasion for devotional watching, or an observance. The Italian word vigilia has become generalized in this sense and means 'eve' (as in "on the eve of the war").
