Abydos Boats and Enclosures Mark the Stars of Cepheus, One of the Argonauts Immortalized in the Stars: Are These The Boats of Jason and his Minyans?
we showed that the Abydos Boats are "docked" at the "harbor" of Cepheus, which is marked in a figure at the Dolmen viz. Tumulus of Mane Lud Locmariaquer in Morbihan, France. See our previous posting on The Dolmen viz. Tumulus of Mane Lud viz. Mané Lud Locmariaquer Morbihan France Deciphered as Marking the Stars of the Vernal Equinox ca. 4320 BC.
The following graphic arguably shows why those boats were docked at Cepheus in ca. 3360 BC, being at a central astronomical location in the era of 3360 BC, not just in terms of the Milky Way, but also with regard to the North Galactic Pole, the North Ecliptic Pole, the North Celestial Pole, and the Winter Solstice, all of which are located on a line that sets off the Cepheus harbor.
We thus consider the era of 3360 BC to be a likely date for the real voyage of the legendary Jason and the Argonauts, coinciding with the start of protodynastic Egypt.
This may relate to the influx of "Gerzeh Culture" into Egypt.
As written in the Wikipedia: "Some symbols on Gerzeh pottery resemble traditional Egyptian hieroglyphs, which were contemporaneous with the proto-cuneiform script of Sumer."

The general topic of ancient seafarers also has to do with significant changes in the European genetic picture, which changed dramatically ca. 4500 B.C., about the same time that we claim that the megalithic calendar was instituted in 4320 BC.
See Ker Than, Modern Europe's Genetic History Starts in Stone Age, National Geographic News, in which the sub-headline is that "Scientists create the first detailed genetic history of modern Europe".
As Ker Than writes:
"DNA recovered from ancient skeletons reveals that the genetic makeup of modern Europe was established around 4,500 B.C. in the mid-Neolithic...."
