Moon magic

There is a belief common to many cultures that working rituals at the time of different phases of the moon can bring about physical or psychological change or transformation.

Such practices are common amongst adherents of neopagan and witchcraft systems such as Wicca.

[1] Witches in Greek and Roman literature, particularly those from Thessaly, were regularly accused of "drawing down the Moon" by use of a magic spell.

The trick serves to demonstrate their powers (Virgil Eclogues 8.69),[2][3] to perform a love spell (Suetonius Tiberius 1.8.21) or to extract a magical juice from the Moon (Apuleius Metamorphoses 1.3.1).

These beliefs would seem to be consistent with many other cultures traditions, for instance; casting of the spell is often done during the full moon's apex.
