Now Ogham is a more mathematical type of ancient language, at least to many.
And often you may find Ogham with other stone carvings, pictographs, petroglyphs, or whatever you choose to call them. Such carvings are usually out of the weather, and often mixed in with more modern carvings like “Kilroy was here” kind of stuff. You might even find some runic ancient language carvings there, too. Every case and situation is different.
It can be rather confusing to many.
