Lietbertus' party encountered dangers as it passed through Bulgaria, Dalmatia, Isauria, arriving at Corinth.

Fearing the ruler of that island, whom they called Katapant and who was the second-in-command, and in order that they not fall into pagan hands, [the bishop] remained there from June 4 until July 31.

[He stayed] until the day when--although he had expended a great deal of gold and believed he had resumed the marine crossing to Jerusalem--he was fraudulently taken back to Laodicea, because the sailors wished to avoid the ambushes of the pagans.
