The Gesta Adalberonis or Gesta Alberonis ("Deeds of Albero") is a biography of Adalbero, Archbishop of Trier (1131–52), written in medieval Latin prose by Balderic of Florennes. There is also a Gesta Alberonis metrica anonyma, an anonymous biography of Albero's life down to 1145, written in hexameters. The Gesta’s account of Albero's youth is mostly legendary, but his years as bishop are reliably covered, especially those portions describing that to which Balderic was an eyewitness. The work is biography and, although the author heeps praise on the subject, it is not hagiography.
