This is about a visit to the ruins of the ancient Ionian city of Teos. These ruins are in what is now the district of Seferihisar, in the province of İzmir, on the Aegean coast of Turkey. On the web there is a lot of information about the site. There is a 28-page illustrated guidebook in Turkish and English (pdf file). However, Ayşe and I did not consult any of this information before visiting. What we had was George Bean, Aegean Turkey (London: Ernest Benn, 2d edition, 1979). Bean himself died in 1977. Once we were at the site of Teos, we learned something of its layout from the posted map.
I am going to describe our visit to the site; and yet one great pleasure of our visit was its unexpectedness. We had come to the area for a short beach holiday before Antalya Algebra Days XVII, which would be held not in Antalya, but at the Nesin Mathematics Village, further down the coast from Teos in the hills above Ephesus. In Istanbul, packing my things for our trip, I finally remembered to check Bean’s book to see what was in the area we would visit. Bean had a number of pages about Teos, along with some enthusiastic words; so I found room for the book in my backpack.
