Leiden University Libraries (UBL) are launching Maps in the Crowd – Atlases, a project that welcomes participation from the public to make accessible eleven atlases with over 300 digitized maps of Asia. The public’s help is invited to improve access to the cartographic collection for education and research.

The Geography, written in the second century CE by Claudius Ptolemy (c. 100 ce- c. 170 ce), described the Earth’s geography through knowledge from Greco-Roman trade routes. The map India beyond the Ganges presented geographical information stretching from the river’s east bank towards China. Although previous studies provided place-names based on cognate comparisons between Ptolemaic data and recent toponyms, the identification of the Ptolemaic eastern limit remains problematic, exemplified by a location known to the ancient Romans as Kattigara, possibly Hangzhou (China) or Óc Eo (Vietnam). My research raises the possibility of Kattigara being located in the vicinity of the Korea Bay, based on a comparison of geographical landmarks such as the river’s mouth and cape. Other possibilities may involve Suvarṇabhūmi and a town called Zabai (Óc Eo). Though geographic recognition of Ptolemaic toponyms has since disappeared, their graphic information is still acknowledged and carries some influence in Southeast Asia, including in maps compiled by European and Arab cartographers in the 12th-16th centuries. These maps are a blend of Ptolemaic place-names and navigational information of their ages, visualising an imaginary continent of Southeast Asia. My presentation will illustrate research on the identification of cartographic information of Ptolemy’s India beyond the Ganges and Chinese lands as the basis for the study of ancient Southeast Asian maps.
