In the 1950s, when Gerald Gardner was writing what eventually become the Gardnerian Book of Shadows, one of the items he included was a list of guidelines called the Ardanes. The word “ardane” is a variant on “ordain”, or law. Gardner claimed that the Ardanes were ancient knowledge that had been passed down to him by way of the New Forest coven of witches. However, it’s entirely possible that Gardner wrote them himself; there was some disagreement in scholarly circles about the language contained within the Ardanes, in that some of the phrasing was archaic while some was more modern. This led a number of people – including Gardner’s High Priestess, Doreen Valiente – to question the authenticity of the Ardanes.
Valiente had suggested a set of rules for the coven, which included restrictions on public interviews and speaking with the press. Gardner introduced these Ardanes – or Old Laws – to his coven, in response to the complaints by Valiente.
One of the largest problems with the Ardanes is that there is no concrete evidence of their existence prior to Gardner’s revealing them in 1957. Valiente, and several other coven members, questioned whether or not he had written them himself – after all, much of what is included in the Ardanes appears in Gardner’s book, Witchcraft Today, as well as some of his other writings. One of Valiente’s strongest arguments against the Ardanes – in addition to the fairly sexist language and misogyny – was that these writings never appeared in any previous coven documents. In other words, they appeared when Gardner needed them most, and not before.
The dispute over the origins of the Ardanes eventually led Valiente and several other members of the group to part ways with Gardner. The Ardanes remain a part of the standard Gardnerian Book of Shadows. However, they are not followed by every Wiccan group, and are rarely used by non-Wiccan Pagan traditions.
