Vi veri universum vivus vici

"Vi veri universum vivus vici" is a Latin phrase meaning: "By the power of truth, I, while living, have conquered the universe."

The phrase may also be written "Vi veri veniversum vivus vici".

This quote is often attributed to Christopher Marlowe's "Doctor Faustus", where it appeared supposedly as "Vi veri ueniversum vivus vici", however no direct citation has been found. Note that v was first the consonantal u, and was written the same before the two forms became distinct, and also after in many cases, when u and v were both capitalized as V: thus, Veniversum. Also, universum is sometimes quoted with the form ueniversum (or Veniversum), which is presumably a combination of universum and oeniversum (two classically-attested spellings)Fact|date=October 2008. The 'V' sounds are properly pronounced as English 'W' sounds in Classical Latin pronunciation. Ecclesial Latin uses Italianate pronunciation, retaining the English-style "v" sound.

Aleister Crowley took this phrase as his magickal motto as a "Magister Templi".

The phrase has recently been made popular by the motion picture "V for Vendetta", where the phrase is embossed onto the surface of a mirror in V's house, and in the original graphic novel where it is above an archway in the house. In the movie version, the main character credits the phrase only to "Faust". In the original graphic novel "V for Vendetta" by Alan Moore, on which the movie is based, the quote is attributed to "a German gentleman named Dr. John Faust."
