The term “itinerarium” (plural: itineraria) comes from Latin and, in a historical context, refers to a route map, particularly used in Roman times. It was essentially a document that listed places (towns, stations, other stops, and landmarks) along Roman roads, often with distances marked between them. It served as a practical travel guide for officials, merchants, and military officers, as well as for pilgrims undertaking religious journeys in Late Antiquity. Unlike modern maps, itineraria were not geographic representations but rather textual or tabular lists—more like a turn-by-turn log than a map. They were often inscribed or written on scrolls and later copied into codices.
