This reminded me of an 2nd century Gaulish artifact found in the late 19th century called the 'Coligny Calendar'
so I went to see if there was mention of any planets and no, there doesn't seem to be.
It gives the gaulish names, in Roman Script, for the:
Months (Calender begins 46 days into our calender')
: SAMON (also called MID SAM)
, DVMAN, RIVROS, ANAGAN, OGRONN, CVTIOS, GIAMONI, SIMIVIS, EQVOS, ELEMIV, EDRINI, CANTLOS
fortnight (14 days): ATENOVX
Their 13 month year: AMMAN
3 days with no moon: TRINoX SAMO sindiv (not sure which is moon I'd assume SAMO)http://www.celticnz.co.nz/Coligny/ColignyPart1.htm
I'd love it if we came upon an astrological chart, or inscribed 'Antithikyra Device'
, of druidic origin that is this significant!
