The Einsiedeln Itinerary is a ninth century guide to the City of Rome written for pilgrims. It was preserved in the Einsiedeln Abbey in Switzerland.
The Itinerary is written in eleven sections. Each section describes a crossing of Rome from one gate to another, describing the interesting sights to be seen on or near the particular route. The text describes many buildings and monuments, and describes in detail the walls of the city.
Historians study the Itinerary to discover information about the activities and motivations of ninth century pilgrims as well as to add detail to historical knowledge of Roman buildings and institutions. An appendix to the Itinerary includes transcriptions from monuments in the city, many of which no longer exist.
History
The Itinerary was written by an anonymous author in Rome. It was later collected in the Einsiedeln Manuscript (Latin: Codex Einseindelnsis) along with four other documents, before being taken over the Alps to Francia.
It is not known precisely when the document was created. It refers to the monastery of Santo Stefano, and so was written after its completion in the mid eighth century. It makes no reference to the Leonine City which was completed about 850 AD, so scholars believe that it was written prior to this.
The document was discovered in the Einsiedeln Abbey in the seventeenth century.
