The English word "libation" derives from the Latin ', an act of pouring, from the verb ', "to taste, sip; pour out, make a libation" (Indo-European root "", "pour, make a libation"). In ancient Roman religion, the libation was an act of worship in the form of a liquid offering, most often unmixed wine and perfumed oil. The Roman god "Liber Pater" ("Father Liber"), later identified with the Greek Dionysus or Bacchus, was the divinity of "libamina", "libations," and "liba", sacrificial cakes drizzled with honey.
