In particular when it says "it was demonstrated in 2017 that the calendar on the Metonic Spiral is indeed of the Corinthian type but cannot be that of Syracuse," although as evidence goes that doesn't sound definitive.
Nevertheless, it is important to remember that Archimedes was part of an active intellectual community and is reported to have written a (now lost) manuscript on the construction of planetarium-style models ("On Sphere-Making"), so whether or not the artifact is directly from Archimedes there might be an intellectual link.
Thanks for posting the link.
Much of my commentary comes from past research on Archimedes... so I am biased and amused.
If I recall the founding of Syracuse is by Spartans and Corinthians... Archimedes society cared enough about knowledge that he was sent to Alexandria to study. Syracuse was a melting pot of cultures from the start and the Phonecians and the roman conflicts reinforced that to the end.
