The Mystic Mark

or the Mark of the Ray of Light, a symbol /|\ devised by Iolo Morganwg to represent the virtues Love, Justice and Truth.

However Iolo himself did not make much use of the symbol and it was after his death that it became increasingly popular. It was first seen on the Proclamation Scroll in Cardiff, 1833. By 1850 it could be seen on the banners in gorseddau and from around 1860 on new members' certificates.

By the end of the century it was considered the approved symbol of the Gorsedd of the Bards and appeared on its programmes, on the new banner and sometimes even on the Gorsedd Stones.

By the 1950s it was decided that the symbol had to be included on every national Chair and Crown.
