Forms

mīliārius (feminine mīliāria, neuter mīliārium); first/second-declension adjective[1][2] Also spelled milliārius.[1][2] Manuscripts nearly everywhere write it with one ⟨l⟩, while older editions print two.[3]

Etymology

It is from Latin mīlle (“thousand”) + -ārius.[1][4][5] De Vaan lists it among the derivatives of mīlle, first found in Varro.[6]

Earliest recorded meaning

It is first found in Varro (116–27 BC),[6][7] of numbers that belong to the thousands and of flocks of a thousand head.[1]

Semantic evolution

In Classical Latin it described anything made up of a thousand units: a cavalry squadron of a thousand men, a slope a thousand paces long, boars weighing a thousand pounds, olive trees said to yield a thousand pounds of oil a year,[1][2][5] and, in an inscription, charioteers with a thousand victories.[1] Tertullian used it of an age of a thousand years.[2][4]

In Augustine the plural mīliāriī named the Chiliasts, who expected a thousand-year reign of Christ on earth.[8] In early medieval charters miliarius became a masculine noun meaning a mile.[9][10]
