baculum

Etymology and origin of the Latin word baculum

Pronunciation

  • IPA (Classical): [ˈba.kʊ.ɫũː][1]
  • IPA (Ecclesiastical): [ˈbaː.ku.lum][1]

Forms

baculum n (genitive baculī); second declension[1]

Etymology

It goes back to Proto-Italic *bak-(k)elo-.[2] De Vaan notes that several languages have words in *bak- for a staff or peg: Old Irish bacc (“hook, crooked staff”), Welsh bach, Ancient Greek βάκτρον (báktron, “stick, staff”) and Germanic words such as Middle English pegge (“peg”).[2][1] Since *b was very rare in Proto-Indo-European and the Celtic forms have an unexplained double consonant, he takes them all to be borrowings from an unidentified source.[2][1] Pokorny and Köbler set up a root Proto-Indo-European *bak- (“staff”).[3][4] Older dictionaries derived it from the root of Ancient Greek βαίνω (baínō, “to go”), as a stick for walking.[5][6]

Earliest recorded meaning

De Vaan and Köbler date it from Cicero onwards.[2][4] In the Verrines Cicero uses it of a lictor's rod, turned round to beat a man in the eyes.[7][5]

Semantic evolution

Its basic sense was a staff or walking stick, unlike scipio, a staff carried for show, and fustis, a stick for beating, although later writers used it for all of these.[5] It named the augur's crooked staff, the lituus,[7][5] and a king's sceptre, including the sceptre of a stage king.[7][5] With pera “wallet” it was the badge of the Cynic philosophers.[5][8] A masculine form baculus appears from Augustan times.[5][9]

In the Vulgate the staff became a figure of support,[8] and Ecclesiastical Latin used it for a crook or rod.[10]

Timeline

  • 81–43 BC – Cicero uses it for a lictor's rod.[7][4]
  • 59 BC–17 AD – Livy uses it for the augur's staff and for the stick with which Tarquin struck off poppy heads.[7][4]
  • 43 BC–18 AD – Ovid has the masculine baculus.[5][4]
  • c. 75–c. 150 AD – Suetonius mentions the sceptre of a stage king.[7][4]
  • 390–406 AD – The Vulgate uses baculus for a pilgrim's staff and, figuratively, for a support.[5][8][4]
