For more than a decade Klaus Geus has held the Chair for the Historical Geography of the Ancient Mediterranean at Freie Universität Berlin, during which he has continuously explored new ways in the study of the Greek and Roman world. Through his immense scholarly output and his extensive network, he has established himself as one of the foremost experts on historical geography.

The present collection of articles by thirty-one scholars from various disciplines is dedicated to Klaus Geus on the occasion of his sixtieth birthday. In line with Klaus Geus' research interests the articles of this Festschrift take the reader on a journey from the imperial court along the Roman roads into the provinces and far beyond the confines of the Mediterranean to the edges of the oikumene: India and Taprobane – Yemen and Ethiopia. On this odyssey through the ancient world particular attention is paid to common sense geography, and Herodotos, Mela, Ptolemy and Strabon are but a few of the Greek and Roman authors accompanying the reader.
