Veillantif
Veillantif (French), Vielantiu (Old French); Vegliantin, Vegliantino or Brigliadoro (Italian) is the name of Roland the paladin's trustworthy and swift steed in the stories derived from the "chansons de geste". The French name comes from an expression meaning "vigilant". "Veillantif" is first mentioned in "The Song of Roland" (v. 2032; laisse 151). Veillantif was given various origins. In the 12th century "chanson de geste" "Aspremont", the horse is said to have formerly been in the possession of King Agolant's son Aumon. After Aumon's defeat, the horse (and his sword Durendal) was given to Roland. Andrea da  Barberino's (1370–1431) Italian prose adaptation "L'Aspramonte" stated that the horse was called Briadoro when it belonged to Almonte (Aumon), but renamed Vegliantino after being conquered by Orlandino ("little Roland"). Luigi Pulci's (1432–1484) "Morgante" refers to the horse as Vegliantino whereas Matteo Maria Boiardo's (1440–1494) "Orlando Innamorato" and Ludovico Ariosto's (1474–1533) "Orlando Furioso" used "Brigliadoro", Italian for "bridle of gold".
