Professor Dr. Renate Pillinger saw our book in the library of the University of Vienna and immediately sent us a remedial bibliography on the cave. She did not know about the Archaeology report cited above, and we did not know—and wished we had—about her own publications. We have now seen, for example, the following important article and apologize for not having known about it earlier: Renate Pillinger, “Neue Entdeckungen in der sogenannten Paulusgrotte von Ephesos,” Mitteilungen Zur Christlichen Archäologie 6 (2000), pp. 16-29.
