Sigil of Amdusias Stainless Steel Necklace

Amdusias is the one who shows up with a full band, and this stainless steel sigil pendant carries that unmistakable energy. He's the 67th spirit of the Ars Goetia, a Great and Strong Duke commanding twenty-nine legions, appearing first as a unicorn before shifting to human form at the summoner's request — a transformation that comes with its own soundtrack.

His signature power is music: he can fill a space with the sound of trumpets and every kind of instrument, heard but never seen, and he's said to be the demon responsible for the discordant music played in Hell itself. He can also make trees bend at will, and his voice is traditionally linked to thunder, said to roll through storms. He grants excellent familiars to those who summon him.

Wear it for creativity, for sound and music work, for a little bit of theatrical, larger-than-life presence — this one's for anyone who wants their entrance to come with a fanfare, phantom or otherwise.

• Material: Stainless steel (tarnish-resistant, hypoallergenic-friendly, built for daily wear)
• Design: Amdusias's sigil from the Ars Goetia, rendered as a 1" pendant
• Chain: 17" length

Who Is Amdusias?

Amdusias (also spelled Amduscias or Amdukias) is the 67th spirit of the Ars Goetia, the first book of the Lesser Key of Solomon, described as a Duke Great and Strong who commands twenty-nine legions of spirits. He first appears in the form of a unicorn, transforming into human shape only when the exorcist commands it — and that shift is accompanied by trumpets and every kind of musical instrument sounding, though never visibly present.

His most distinctive trait, consistent from Johann Weyer's 16th-century Pseudomonarchia Daemonum through the later Ars Goetia, is command over sound itself: phantom concerts of unseen instruments, and the ability to make trees bend and incline according to the summoner's will. Later folklore expands on this, casting him as the demon in charge of the discordant, cacophonous music played throughout Hell, and linking his voice to the sound of thunder during storms. He's also credited with providing excellent familiars to those who call on him.

Depictions have varied over the centuries — some show him as a human figure with claws and a unicorn's head, crowned, surrounded by musical instruments that can be heard but not seen, which became the standard image popularized by 19th-century illustrator Louis Le Breton in the Dictionnaire Infernal.
