Aradia

Two overlapping strands appear in the sources. In Charles G. Leland's 1899 book Aradia, or the Gospel of the Witches, Aradia is presented as a daughter of Diana (and in Leland's narrative linked to Lucifer) sent to earth to teach oppressed people witchcraft as a means of liberation; Leland frames his text as a 'Gospel' of a Tuscan witch tradition. Separately, comparative folklorists (including Magliocco and Eliade in cited summaries) trace cognate names in Italian and Sardinian records (Arada/Araja/s'Araja) and identify an association with the medieval figure Herodias (Italian Erodiade), who in medieval tradition becomes a nocturnal spirit condemned to wander the sky. Scholars note that Leland's claims about a continuing Tuscan witch religion and the provenance of his text are disputed by historians, and that regional traditions show multiple, sometimes divergent, local forms rather than a single unified origin.

Leland's narrative emphasizes Aradia's role and origin (daughter of Diana) rather than providing a detailed physical description. Medieval and folkloric accounts that connect cognate names to Herodias/Diana's train describe the related figures functionally as nocturnal, flying women who wander the sky and rest in treetops between midnight and dawn; appearance in those contexts is therefore tied to nocturnal flight and membership in a female supernatural company rather than to a consistent personal portrait.

In Leland's text Aradia functions as a teacher of witchcraft, instructing those who 'fain would study witchcraft' and promising liberation from slavery; the Gospel contains spells and invocations and an account of witches' meetings (Leland's 'Tregunda' or Sabbat) which he said outlined doctrine and rites. In wider folkloric materials cognate figures are associated with night-journeys and aerial movement as members or patrons of Diana/Herodias's nocturnal train; Eliade's summary links Arada/Irodiada with a Romanian 'Queen of the Fairies' who patronized ritual dance groups (calusari). Sources stress that Leland's literary presentation and folkloric attestations are distinct kinds of evidence and that the extent to which Leland preserved preexisting folk belief is contested.
