Many thanks for posting this article.  The Antikythera mechanism is a fascinating Instrument indeed, the Stellarium of its time (analog rather than digital, of course).  I've found a relatively recent book about it, which is very interesting and quite comprehensive:

Alexander Jones

A Portable Cosmos: revealing the Antikythera mechanism, scientific wonder of the ancient world.                     

Oxford University Press, 2017, ISBN: 9780199739349

I 'm sorry I don't have a PDF version of the book, as it is a recent copyrighted publication. However, the author, who is the head of New York University's Institute for the Study of the Ancient World (ISAW), gave a lecture on this device which is available free of charge from the NYU website. The lecture was associated with a very appealing small exhibit on time and timekeeping in the Greco-Roman world.

The link to the lecture is:

The ISAW galleries remain closed, but I hope that in the not very distant future we'll be able to attend exhibits once again.
