Fifteen Pictish Symbol Stones with linear Ogham inscriptions and one circular (Logie Elphinstone) have been identified from The Pictish Symbol Stones of Scotland edited by Iain Fraser (RCAHMS 2008). Whether the inscriptions have a “belief” context is inconclusive from material so-far researched.
All the Ogham inscriptions on Pictish Symbol Stones are incised appearing as additions and seemingly not an integral part of the original overall designs – that in itself does not lend any further indication to dating of the Symbol Stones themselves.
In each case there appears to be no specific positioning relative to a Pictish Symbol – except where the Ogham is on the narrow side of a Stone suggesting a decision to not place on the already decorated surfaces (sometimes perhaps due to space restrictions).
