By Patrick Hunt –
“Alexander was hunting on Mount Pagos, and that after the hunt was over he came to a sanctuary of the Nemeses, and found there a spring and a plane-tree in front of the sanctuary, growing over the water. While he slept under the plane-tree it is said that the Nemeses appeared and bade him found a city there and remove into it the Smyrnaians from the old city . . . So they migrated of their own free will, and believe in two Nemeses instead of one, saying their mother is Nyx…” 
This above passage of Pausanias is not well attested elsewhere, but it does agree in part with several extant traditions of Alexander at Smyrna and is also detailed on Roman Era coins from Smyrna.
Mount Pagos is the present day ridge of Kadifekale on the southeastern hill of Izmir (Smyrna), today marked by Turkish fortresses and historic vistas with occasional wooded park preserves. The Hellenistic city of Smyrna does not share the same locus as the earlier Archaic city was besieged and razed by Alyattes (seventh to sixth c. BCE), the Lydian Mermnad ruler, around 600 BCE;  the earlier city being on the north side of the old Hermes River across the bay and the newer city associated with Alexander on the south side of the bay,  which location, according to Strabo, was 20 stadia (roughly 4 kms) distant from the old Smyrna (see below). We know Alexander was at Smyrna and ordered at least its “restoration” after the Lydian takeover,  or that, more likely following the ideas of the legendary dream, his successors Lysimachos and Antigonus did the actual reorganizing (“reassembling”) according to Strabo (Geography 14: 1.37) 
Since the founding story of Hellenistic Smyrna that Pausanias relates is also on the Roman Era coins, many minted from the mid-third c. CE under Philip the Arab, it confirms at least the legend rather than fact. As Karsten Dahmen notes, “looking at the coins, we find every detail mentioned in this story.”  The double Nemeses at Smyrna were an old civic tradition, and Dahmen also suggests that the twin goddesses may represent “an echo of a statue group of these goddesses erected in Smyrna”.
There is also remnant epigraphic evidence of Smyrna’s twin Nemeses still seen in the Agora of Roman Era Smyrna, as I saw recently on November (see below photo). One can still read, on a white marble block of a presumed architrave, a dual line above dentils. This fragmentary inscription reads NEMESE[__] in the above line and TON SEBAST[__]…on the lower line. That it is a dual Nemesis is manifest in the final remnant “E” in the name rather than a singular “I”.  Although the full context is not given here, that there was a shrine and altar to Nemeses at Smyrna is also known, and Tataki associates Nemesis contexts with gladiatorial games at Smyrna  since she was also a patroness of gladiators. Many accounts have placed the Nemesis shrine up on Mt. Pagos itself rather than around the Agora where the fragmentary inscription is now placed within the Agora enclosure, but Tataki’s study offers the most relevant contexts. In my photo, the Pagos Hill (Kadifekale) can be seen on the high horizon behind the mounted inscription, a hill covered with cypresses (near the enormous Turkish flag on the summit).
The old Greek goddess Nemesis, daughter of Night by many but not all accounts, was a deity of divine retribution often believed to punish hubris and make proportional balance for an excess of one-sided good fortune (Tyche), especially when improperly appropriated or not sufficiently respected.  In other Greek myths Nemesis, not Leda, is the actual mother of Helen of Troy and that Leda merely found the resulting egg from the mating of Zeus and [winged] Nemesis (Pseudo-Apollodorus, Bibliotheca 3.127; Pausanias, Description of Greece 1. 33. 4 in his description of Rhamnous’ Nemesis Temple although Pausanias is not alone in naming Okeanos as the father of Nemesis). Although this deity was also at times perceived as a duality to be begin with (Nemesis-Tyche), it also makes some sense that Smyrna would have a dual deity – one kindly, one implacable – for this balancing role especially since some suggest there was a Nemesis for both the old city of Smyrna and the new one. At least one other suggestion about Nemesis is that she was not even Greek but Anatolian and originating here around Smyrna. The so-called Tyche of Alexander is already well published elsewhere,  but his presumed willingness to obey in to the legendary dream would also make sense given his quest for conquest of Asia and his perceived need for divine allies. Antiquity is not the only time when the duality of Nemesis is manifest: Albrecht Durer’s famous 1502 serene Nemesis (so named from his notebooks) but ambiguously subsequently also referred to as The Great Fortune, is balanced deliberately precariously on a small globe with insufficient room for both feet and one foot apparently slipping off, exhibits both the cup of blessing and the bridle for either necessary response.
In 1843 Antoine Chenavard published a Smyrna Agora view of one surviving side of the row of Roman columns on their pedestals. In his foreground are the beautifully-carved Ottoman Islamic cemetery headstones, now moved but also still seen at the Agora on the southeast side, as in my photo below, showing the Turkish respect for archaeological remains and religious artifacts from all periods, including their own Ottoman history.
According to the same Alexander-Nemeses legend, after hearing of Alexander’s dream, the people around Smyrna inquired of the Oracle of Apollo at Claros  (also see Ovid Metamorphoses XI.413) in Ionia north of Kusadasi and were told they would be three or four times happier than previously if they moved their city from the old to the new location beyond the sacred Meles Stream. Although it is hard to configure the watershed of the ancient stream through the much-disturbed Izmir contexts, there are residual springs like the possible old Meles (modern Yeşildere?) whose waters still flow underground down from Kadifekale’s (Pagos) plateau through the much-disturbed Agora as the trickle can still be seen in the arcaded “Cryptoporticus” there below the ground level Agora.
As a somewhat ironic concluding aside here, when I was a graduate student at the American School of Classical Studies at Athens, one of our archaeological study visits was to Rhamnous, famous for, as mentioned, among other sanctuaries, the unfinished but utilized fifth c. BCE Nemesis sanctuary.  At the time, I took many photos of this Nemesis context, and to my uneasy chagrin, this particular rolls of slide film in 1984 was so damaged that these photos were ruined and only partly visible, the only time this has ever happened to my photos.  At the time, I took it as somehow apropos for me personally. Fortunately, and I assume equally apropos, the 2012 Smyrna photos of this local Nemeses artifact came out perfectly fine. I feel particularly good about this second event, but not overly so.

 I still show these ruined photo images in my classes as both a tongue-in-cheek example of Nemesis to my students and a healthy check to myself.
