Abstract
The progression in the naming of the seven cities from south to north and along the coast now changes, and the direction is now southeasterly, into the interior. Thyatira was in the region called Lydia, on the Lycus River, on the road which led from Pergamum to Sardis. This was the main road from Pergamum to the east, and Thyatira, in periods of peace and prosperity, thus enjoyed its important location. In times of war, however, Thyatira's situation was of strategic importance, and would be attacked by any invader from the east. Unprotected by the land, without an acropolis, the city was by nature weak.
