Saint Lucanus of Sabiona or Lucanus of Säben (Italian: San Lucano or Lugano; German: Lukan von Säben; fl. 5th century; died 20 July), is a Roman Catholic saint of the fifth century, associated with the Dolomites and the Tyrol.
He is often described as bishop of Säben, and later—erroneously—as bishop of Brixen in the South Tyrol.
Lucanus is scarcely known outside the immediate area of his labours and much that is said of him is legendary.
He is said to have been a bishop of Säben, earlier Sabiona, above Klausen, in the first half of the 5th century (the bishops moved to Brixen in the 10th century).
During a famine he allowed the consumption in his bishopric during the forty days' fast of Lent of milk, butter and cheese if they could be obtained. For this his enemies denounced him in the year 424 before Pope Celestine I, who ordered him to Rome. Lucanus set out, despite his advanced age, accompanied by a single servant. On the way his horse was killed and eaten by a bear: Lucanus commanded the bear in the name of God to take the horse's place, and then saddled and bridled it and rode it to Rome.
Stopping overnight at an inn in Spoleto, Lucanus discovered that the landlord's wife was bedridden with dropsy, and cured her by praying at her bedside.
He continued to Rome, and ordered a flock of partridges to fly ahead of him to the Pope as a gift, since he had nothing suitable to give him. When he arrived in Rome for his audience he wanted to take off his cloak, which was wet from the rain, but found nowhere to hang it, so threw it over a ray of sunshine, which supported it. When the Pope saw that Lucanus was in grace he declared him innocent and allowed him to return home with his blessing and rich presents.
