By examining the latitude values for the sites which are listed in the above table, it becomes clear they are largely decreasing in value as one progresses down the list. However, the first three locations, namely Othonae (Bradwell-on-Sea), Dubris (Dover) and Lemannis (Lympne), form one sequence which runs southwards down the coastline. The remaining six sites form a distinct continuous sequence also following the coastline. This may indicate two sources for the list, arising from two periods of fort construction.

The Sicyonian kings

Eusebius of Caesarea stated:

From the latter [Sardanapallus] until the first Olympiad 67 years elapsed … Thus it turns out that the [total] duration [of the Assyrian kingdom] was 1,280 years.

Chronography of Eusebius 15

The document says Sardanapallus was the last Assyrian ruler. As the first Olympiad was held in 776 BCE it follows that the Chronography was asserting that the first ruler started his reign in the year 2123 BCE. Later on, the text lists the kings of the Sicyonians:

Aegialeus, 52 years. The Peloponnese was originally called Aegialeia, after this Aegialeus. He is said to have started to rule Sicyon in the 15th year of Belus, the first king of the Assyrians. According to legend, [Belus] was the son of Poseidon and Libya.

Chronography of Eusebius 63.

We may conclude that Aegialeus’s rule started in the year 2109 BCE. The list gives the following lengths of reign from which we may derive the dates of their commencements:

Eusebius then adds:

There were a total of 26 kings of Sicyon, who reigned for 959 years. After [Zeuxippus], there were no more kings. Instead the priests of [Apollo] Carneius [ruled].

Following this list Eusebius says:

The total for the Sicyonian kings and priests is 998 years.

Alternative dates for the Trojan war

Polypheides was the Sicyonian king at the time of the Trojan war which means it occurred some time between 1232 and 1202 BCE. 1218 BCE, the date indicated by the eclipse data, lies in that range.
However, we can analyse the information by starting with Assyrian chronologies. The rule of Bel-bani, identified with Belus, started c. 1700 BCE. So, the first Sicyonian king, Aegialeus, ruled from c. 1686 BCE. The sum of all the reigns from his rule to that of Polypheides,the Sicyonian king during the Trojan war, is 877 years. This means Polypheides ruled from around 809 to 778.
