Forms
eculeus m (genitive eculeī); second declension[1] It is also spelled equuleus.[2][1]
Etymology
It is from Latin equus (“horse”) + -uleus.[2][3] De Vaan traces equus to Proto-Italic *ekwo- (“horse”) and Proto-Indo-European *h₁eḱ-u- (“horse”), comparing Sanskrit अश्व (áśva-, “horse”) and Ancient Greek ἵππος (híppos, “horse”).[4]
Earliest recorded meaning
De Vaan dates it from Varro,[4] who in his Menippean satires says that a groom will not break in a wild foal.[2]
Semantic evolution
It is a young or small horse, a foal or pony: Livy reports among prodigies that a cow gave birth to a foal, and Cicero mentions little silver horses as works of art.[2] It is also an instrument of torture, probably a kind of rack: Cicero speaks of an inquiry into the facts on the rack and of a man tortured on it, and Seneca mentions it in his letters.[2] Köbler dates it from Cicero.[3]
