According to new-age religious scholar James R. Lewis, in his book "Witchcraft today: an encyclopaedia of Wiccan and neopagan traditions", a high priestess becomes a queen when she has successfully hived off her first new coven under a new third-degree high priestess (in the orthodox Gardnerian system). She then becomes eligible to wear the "moon crown". The sequence of high priestess and queens traced back to Gerald Gardner is known as a lineage, and every orthodox Gardnerian High Priestess has a set of "lineage papers" proving the authenticity of her status.
