A unicorn who then takes human form; at his command sound concerts of trumpets and instruments, heard but not seen.

He makes all kinds of music sound, bends trees at will, and gives excellent familiars.
Amdusias appears in Weyer as Amduscias, within the series of spirits that the Ars Goetia reworks and orders with seals. The Goetia preserves his ducal rank, his initial unicorn form, and the motif of invisible music and bending trees. Already attested in the Liber Officiorum Spirituum (Folger V.b.26, 16th c.) as «Deyclo alias Deyoo (?)».
Amdusias's main seal follows the printed Mathers–Crowley (1904) form; the Sloane MS 2731 manuscript facsimile is shown separately for comparison.

MacGregor Mathers and Aleister Crowley's 1904 edition, using the normal vector pack documented on Wikimedia Commons (public domain/CC0). The Sloane MS 2731 facsimile remains separate for comparing manuscript variants; it is not used as the main image.
The FULL manuscript facsimile («Lemegeton, Clavicula Salomonis», Sloane MS 2731) is in our library; the original is held at the British Library (Sloane MS 2731).
According to the Ars Goetia, the operation is the same for all 72 spirits:
The instruments are heard without being seen; no particular hour, direction, offering, or ritual warning is preserved for him.

The common Goetic operation also adds, when needed: to constrain a resisting spirit (Wellcome MS 110, c74–c78), to show it the Pentacle of Solomon once manifested (Ars Theurgia-Goetia), to work in its planetary hour and day (by rank), and finally to give it licence to depart —and never before (Wellcome MS 110, c53). Practise the full rite at The Practitioner's Table.

Some modern lists classify him by the element air; the ancient source gives only his rank, appearance, office, and number of legions.
In contemporary demonolatry, practitioners describe the presence of Amdusias as intense and linked to the forces of nature, possessing a temperament that oscillates between the inspiring and the martial. According to S. Connolly, he is frequently worked with to foster musical appreciation and reveal ancient wisdom through dreams, as well as for execration magick operations that demand aggressiveness and strategic precision.

Amdusias is one of the 72 spirits catalogued in the Ars Goetia (the first book of the Lemegeton, 17th c.) and in Weyer's Pseudomonarchia Daemonum (1577); it is listed with the rank of Duke. It is not a deity or a biblical figure: it is an entry in these historical spirit-catalogues.
The seal image of Amdusias that we display and offer for download follows the printed Mathers–Crowley (1904) form, using the normal vector pack documented on Wikimedia Commons (public domain/CC0). The Sloane MS 2731 manuscript facsimile is provided separately because Lemegeton witnesses preserve variants.
Amdusias is a Duke, ruling 29 legions of spirits according to the Lesser Key of Solomon.
According to the ancient sources (the Lemegeton, the Pseudomonarchia Daemonum), Amdusias is summoned with the goetic rite: the Circle and the Triangle of Art are traced, its seal is engraved and worn, the candles are lit and the conjuration is spoken by the divine names; if it delays, it is constrained, and at the end it is given the licence to depart. This is historical-documentary material, not a how-to for real summoning.
He makes all kinds of music sound, bends trees at will, and gives excellent familiars.
Amdusias appears in Weyer as Amduscias, within the series of spirits that the Ars Goetia reworks and orders with seals. The Goetia preserves his ducal rank, his initial unicorn form, and the motif of invisible music and bending trees.
The enn of Amdusias circulating today is «Denyen valocur avage secore Amdusias». It is a MODERN demonolatry chant (late 20th c.); it does not appear in the old grimoires.
