Ogham pendants are historically inaccurate The "Celtic Astrology" pendants are quite attractive, but the purported history given for them is patently false. Ogham script does not predate 400 BC, so did not exist in pre-Christian times. The only known surviving examples are carved in stone, not trees or wood. Neither was there ever a Celtic lunar/astrological calendar based on Ogham. This idea was fostered by a writer named Robert Graves, and his "research" is roundly dismissed by modern scholars. For confirmation, google a number of reputable websites, including cura.free.fr/xv/13ellis2.html by Peter Beresford Ellis. – Richard McLean, 2008-12-26

Ogham The jury is still out on the validity of the Tree Calendar, but it should be noted that Julius Caesar mentioned the use of Ogham in use by the Druids in Gaul (France) during his experience there. The timeframe was in the 1st Century (BCE). It should be noted that Peter Beresford Ellis is regarded in some circles as a Johnny-Come-Lately who has been attempting to make a name for himself as the 'end all' scholar on all things Celtic. In Irish culture Ogham is widely held to be of early origins used for communication. The physical imprints would not have survived except on stone due to age and weather; a little common sense here please. Tree lore and Sacred Groves were and are held dear, so this jewelry should be appreciated for the art it is. – Kat Leannan, 2009-12-19

:Let the scholars debate The scholars can debate the accuracy of the validity of the tree calendar and when the Ogham was first used until the sacred cows come home. The bottom line is this is a nice piece that is well made and durable. I actually lost it while dragging a road on my ranch and it laid out in the dirt and elements for 6-8 months. When I found it again, washed it off and it was as good as new. – Mark, 2011-01-01
