Ogham is a form of alphabet used in ancient times in Ireland and Britain. It consisted of various groups of parallel lines cut into the edge of a stone, with the combinations making up to either 20 or 25 letters. The lines were either slanted upwards to the right, horizontal, or downward to the right, allowing for a variety of letters to be created with just a few marks. "An Ogham" might refer to an inscription in this language.
