The Breviary of Alaric (Breviarium Alaricianum or Lex Romana Visigothorum) is a collection of Roman law, compiled by Roman jurists and issued by referendary Anianus on the order of Alaric II, King of the Visigoths, with the approval of his bishops and nobles. It was promulgated on 2 February 506, the 22nd year of his reign.
The code, however, appears to have been known amongst the Visigoths by the title of Lex Romana or Lex Theodosii, and it was not until the 16th century that the title of Breviarium was introduced to distinguish it from a recast of the code, the Lex Romana Curiensis which was introduced into northern Italy in the 9th century for the use of the Romans in Lombardy. This recast of the Visigothic code was published in the 18th century for the first time by Paolo Canciani in his collection of ancient laws entitled Barbarorum Leges Antiquae. Another manuscript of this Lombard recast of the Visigothic code was discovered by Gustav Friedrich Hänel in the library of St Gall. five books of the Sententiae Receptae of Julius Paulus. Until the discovery of a manuscript in the chapter library in Verona, which contained the greater part of the Institutes of Gaius, it was the only known work containing the institutional writings of Gaius, an important ancient Roman jurist.
