Calas comes from the same root as caled, Welsh for “hard,” and means “solidity.”
As an element, calas is the source of form, differentiation, manifestation, and stability. Its image in nature is stone.
Druid Revival lore contains a set of three elements that first appears in Iolo Morganwg’s writings. Whether it’s an invention of Iolo’s or a surviving scrap of some older teaching is anyone’s guess, but the three elements have been part of Druid Revival teaching ever since his time. Their names are Nwyfre, Gwyar, and Calas.
Detail: The name Calluna derives from the Greek word kallunein which means “to beautify and cleanse”, which probably derives from the use of Calluna Vulgaris (Heather) twigs as brooms, or from its medicinal properties for treatment of a number of internal disorders.
Calluna Vulgaris is an herb of immortality, and protection. Its Invocatory can be Isis, Osiris, or Venus. It is associated with Midsummer’s Eve.
Detail: Traditionally it belonged to one of the three Magi (the Three Wise Men of the Christian nativity story). The name is also associated with the children’s cartoon character Casper the Friendly Ghost.
