Wallace Stevens (New England Verses X):
Ashen man on ashen cliff above the salt halloos
William Shakespeare, Coriolanus (I.viii.7):
If I fly, Marcius,/Halloo me like a hare.
Hello is alternatively thought to come from the word hallo (1840) via hollo (also holla, holloa, halloo, halloa). The definition of hollo is to shout or an exclamation originally shouted in a hunt when the quarry was spotted: Fowler’s has it that “hallo” is first recorded “as a shout to call attention” in 1864.
