Witchcraft, folklore, occult philosophy, the occult arts, mythology, local history, wortcunning, sorcery, alchemy and lifelong student of nature!
Dead people and faeries. Also the deceased Robert Cochrane, late Magister of the Clan of Tubal Cain - long may his legacy live on!
Definitely folk - the four letter word of all spectrums - whether about maidens awaiting their long lost lovers on the shores or pixies dancing about mushrooms! Sandy Denny, early Fairport, Fotheringay, Pentangle, Trees, Midwinter, Stone Angel, Gryphon, Shelagh McDonald, June Tabor, Eighteenth Day of May, Circulus & Secret Green. Not too keen on the finger-in-your-ear type though...
Anything by David Lynch, also the obvious, such as Wicker Man, Hammer Horror, and so forth. None of that god awful tripe that we're bombarded with nowadays though...
The 1980's Robin of Sherwood series, Children of the Stones, and the like. Other than that I watch little TV.
Mainly non-fiction. Currently reading Carlo Ginzburg's 'Ecstasies: Deciphering The Witches' Sabbath', Leland's 'Roman Etruscan Remains', and Jacob Boheme's 'Six Theosophic Points'.
