Pronunciation

  • Classical: [wiːˈpɛ.re.ʊs][1]
  • Ecclesiastical: [viˈpɛː.re.us][1]

Forms

vīpereus (feminine vīperea, neuter vīpereum, adverb vīpereē); first/second-declension adjective[1]

Etymology

It is from Latin vīpera (“viper”) + -eus.[2][1] For vīpera de Vaan rejects the old explanation, going back to Pliny, as ⟨vīvo-para⟩ “bearing live young”, on grounds of meaning and form; he prefers, as conceivable though not fully transparent, Proto-Italic *weip-es-ā- from Proto-Indo-European *ueip-es-, a root meaning “to swing, agitate”, also seen in vibrō.[3]

Earliest recorded meaning

Köbler records it first in Virgil,[4] who gives Discord vipereum crinem, “snaky hair”, bound with bloody ribbons.[2][5]

Semantic evolution

It means of or belonging to a viper or similar snake, as Ovid's carnes and dentes and Lucan's venenum.[2][5][6] It is used of mythological serpents and dragons, especially the dragon that Cadmus killed, whose teeth Ovid has sown as vipereos dentes.[2] Of awe-inspiring beings it means made of vipers, snaky, as the hair of Discord in Virgil and the arms of a Fury in Ovid; by extension it is applied to the beings themselves, so that Ovid calls the Furies vipereas sorores and Medusa's head vipereum monstrum.[2][5][6] In medieval British writers it also means viperous, venomous, malignant.[7]

Timeline

  • 70–19 BC – Virgil gives Discord vipereum crinem.[2][4]
  • 43 BC–18 AD – Ovid uses it of the dragon's teeth sown by Cadmus and of the Furies.[2][5]
  • Medieval Latin – It takes on the sense venomous, malignant.[7]
