Bronze types from Ptolemy I - IV published to PCO

The ANS coins with Svoronos references have been exported from our curatorial database into MANTIS. Nearly six hundred bronzes have been linked to the new PCO URIs and integrated into's SPARQL endpoint for query and analysis. There are now about 3,200 Ptolemaic coins linked to PCO, more than half of which have come from the ANS collection. Both the British Museum and Bibliothèque nationale de France have contributed more than 600 coins, and another nine institutions of varying sizes have contributed the remainder.
