This is an addendum to an earlier essay on the Purāṇic cosmograph interpreting it in terms of the principles of stereographic projection: Kloetzli (Hist Relig 25(2): 116–147, 1985). That essay provided an approach to understanding the broad structures of the Purāṇic cosmograph but not the central island of Jambudvīpa or its most important region (varṣa) of Bhārata. This addendum focuses on the works of Ptolemy as a resource for understanding the Purāṇic materials. It reaffirms the broad outlines of earlier conclusions, (...) but by understanding the major concerns of Ptolemy’s Geography, is able to provide a far ranging interpretation of the Purāṇic central island of Jambudvīpa. Viewed in the light of the main features of Ptolemy’s Geography, Jambudvīpa, the central island of the Purāṇic cosmograph, can be seen as a geograph modeled on the principles of Ptolemy’s Geography embedded within a larger cosmograph modeled on the principles of Ptolemy’s Planisphaerium—the earth at the center of the universe. Parallels between the seven Ptolemaic climates and the Purāṇic varṣas, the Nile and the Ganges, and the inhabited world (oikumene) and Bhārata deepen our sense of shared tradition as do representations of Bhārata alternately as Alexandria and Babylon.
