Forms
auspex m (genitive auspicis); third declension[1]
Etymology
It is a compound of avis (“bird”) and -spex (“who looks”), from speciō (“to look”); de Vaan derives it from ⟨*au̯i-speks⟩, as auceps “bird-catcher” is from ⟨*au̯i-kaps⟩.[2][3][4] The first part goes back to Proto-Italic *awi- (“bird”) and Proto-Indo-European *h₂eu-i- (“bird”), the second to Proto-Italic *speks (“who sees”) and Proto-Indo-European *speḱ- (“who sees”).[2]
Earliest recorded meaning
De Vaan and Köbler date it from Plautus,[2][5] who uses it of the functionary at a wedding: a bride will go to be married without waiting for the auspices.[3][6]
Semantic evolution
Its first sense is the one who takes omens from the flight, cries or feeding of birds, an augur or diviner;[3][4] Lewis & Short note that it is much rarer than augur in this literal sense.[3][4] Cicero names the proposers and auspices of a law, and Pliny the Elder transfers it to the birds themselves, calling the cocks the auspices of all Rome's victories.[3] At a wedding the auspex was a functionary, apparently once the one who took the auspices;[3][6] Cicero has a mother-in-law marry her son-in-law with no auspices and no witnesses.[3][6] From this it came to mean a patron or supporter: Virgil has sacrifices offered to the gods as patrons of work begun.[3] The scholia on Juvenal explain it as the groomsman.[6]
