De situ terrae sanctae

De situ terrae sanctae is a short 6th-century report of a pilgrimage to the Holy Land. Its author is identified in a 9th-century manuscript (Codex Vaticanus 6018) as a German archdeacon named Theodosius.

The work includes a list of places and routes, and occasionally commentary on relevant biblical passages, combining the genre of itinerarium with stories reminiscent of a  modern travelogue. It was compiled after 518 and before 530, as the author is aware of the construction work done under Emperor Anastasius I ((r. 491 – 518)), but not of that done under Justinian I ((r. 527 – 565)).

Theodosius' additional sources
Tsafrir (1986) has argued that the topographical information in the work is based on maps used by tour guides, also reflected in the Madaba Map of the same period. The author inserted additional information based either on his own travels or on accounts by other pilgrims.
