In the legends of the Canton of Jura, Switzerland, Augenbrand is a black dog with fire eyes that prowls near the old Soyhières bridge over the Birs (now destroyed), where he searches for his master, Count Rodolphe de Sogren, who was murdered in 1233. He is reputed to pursue wayward travelers.
This dog's fiery eyes earned him the name Augenbrand: their glow is unmistakable.
Rodolphe de Sogren was Count of the Château de Soyhières (Soyhières was formerly called Saugern in German, a name close to Sogren).
In 1855, Augenbrand was mentioned in the Canton of Jura legends:
The same dog is also mentioned in the Swiss Archives of Folk Traditions (Schweizerische Gesellschaft für Volkskunde in German).
