[1] He is often identified with the Dietrich to whom John of Würzburg dedicated his Descriptio terrae sanctae, another guide to Palestine.
[3] Dietrich's pilgrimage can be dated to between 1171 and 1173, during the reign of King Amalric of Jerusalem, when the Holy Places were under Christian control.
He may have made a detour to visit Nazareth, Tiberias and Mount Tabor, but his description of the Sea of Galilee is very confused.

Dietrich shows less interest in miracles and wonders, but does provide a first-hand account of the coming of the Holy Fire.
