About The Ogham Grove
The Ogham Grove is a modern way of working with the Ogham, as both a year wheel and as a sacred circle, or grove; for both solitary rituals and group work within a sacred landscape - and as an internal, astral sanctuary, within one's own mind - one's inner grove.
Whilst the Ogham Grove is a modern way of working with the Ogham, it is based upon the oldest known tree sequence attributed to the Ogham; that which was recorded in The Scholar's Primer - compiled into the Book of Ballymote c. 1390 AD.
The oldest evidence of the Ogham writing system is that of inscribed pillar-stones; the oldest of which appear to date to the 4th century.
Simply, the Ogham Grove is created by placing the trees of the Ogham, evenly spaced every 18 degrees, around a circle. When one does this, all manner of meaningful patterns begin to emerge, aligning trees with specific stars, deities, and times of the year.
