Different cartographic material, which represented more useful tools for the traveler, were the [[itinerarium]], which listed in order the names of towns between two points, and the [[periplus]] that did the same for harbors and landmarks along a seacoast.{{cn|date= February 2024}}

Later maps of the T-and-O conceptual format featured many rivers and cities of [[Eastern Europe |Eastern]] as well as [[Western Europe]], and other features encountered during the [[Crusades]]. Decorative illustrations were also added in addition to the new geographic features.  The most important cities would be represented by sketches of fortifications and towers in addition to their names, and the empty spaces would be filled with mythical creatures.{{cn|date= February 2024}}
