Amdusias: The Demon of Music, Trees, and Hidden Power

Amdusias, also known as Amduscias, is a Fallen Angel and the 67th of the 72 Spirits of Solomon. In the Goetic tradition, he is described as a great duke of Hell who commands 29 legions of demons.

Amdusias is a strange and powerful spirit whose presence is connected with music, sound, movement, command, and the forces of nature. He first appears in the form of a unicorn, a rare and symbolic image that sets him apart from many other Goetic spirits. The unicorn form suggests mystery, wildness, purity turned uncanny, and a power that is difficult to capture or fully understand.

Appearance of Amdusias

Amdusias first manifests as a unicorn. This form is unusual within demonological tradition and gives him a distinctly otherworldly character. The unicorn is often associated with untamed spiritual force, hidden knowledge, and magical rarity, but in the case of Amdusias this image takes on a darker and more commanding tone.

If commanded, Amdusias will take on human form. When he does so, invisible music is said to be heard. Instruments play, yet no musicians can be seen. This eerie detail makes Amdusias one of the most atmospheric and mysterious demons of the Goetia.

His presence is not silent. It announces itself through sound.

Powers and Abilities

Amdusias is strongly associated with music and unseen instruments. When he appears in human shape, the air fills with music from invisible sources, suggesting his command over sound, vibration, and atmosphere.

He is also said to have power over trees. At the sound of his voice, trees sway, as though moved by a hidden wind or compelled by supernatural command. Amdusias can give people the power to make trees fall, placing him in connection with the living forces of nature, destruction, and command over the physical environment.

In addition, he is said to provide excellent familiars. In magical tradition, a familiar may serve as a spirit helper, assistant, messenger, or guide. This makes Amdusias significant not only as a spirit of music and force, but also as one connected with magical service and occult companionship.

Amdusias and the Mystery of Sound

Amdusias reveals the occult power of sound. His music is not ordinary entertainment; it is unseen, disembodied, and supernatural. It suggests that sound itself can become a sign of spirit presence.

In many magical traditions, sound is deeply sacred. Words, chants, names, vibrations, invocations, bells, drums, and songs can all shape spiritual atmosphere. Amdusias belongs to this mystery. He is a demon whose manifestation is heard as much as seen.

The invisible instruments associated with him remind us that the unseen world does not always appear visually. Sometimes it moves through vibration, tone, pressure, rhythm, and sound.

Amdusias and the Power of Nature

Amdusias also has a connection with trees, especially their movement and destruction. Trees sway at his voice, and he grants the ability to make them fall. Symbolically, this suggests power over rooted things, established structures, and forces that appear immovable.

A tree is deeply grounded. It is stable, old, and rooted in the earth. For Amdusias to make trees move or fall is to show command over what seems fixed. He is therefore a spirit of disruption, force, and supernatural authority over nature.

This power should be understood with caution. Amdusias is not a gentle woodland spirit. His relationship with trees is commanding and potentially destructive.

Amdusias in Demonology

As the 67th Spirit of Solomon, Amdusias occupies a distinctive place in the Goetic hierarchy. His rank as duke gives him authority, and his command over 29 legions marks him as a powerful figure within the infernal order.

He is especially interesting because his powers are not limited to one simple category. He is linked with music, shape-shifting, nature, destruction, command, and familiars. This makes him a complex demon whose symbolism touches several important areas of occult study.

Amdusias represents the hidden music of the unseen world, the voice that shakes trees, and the power that turns atmosphere itself into a sign of supernatural presence.

The Mystery of Amdusias

Amdusias is a demon of sound, command, movement, and wild supernatural power. He appears first as a unicorn, transforms into human form, fills the air with invisible music, and causes trees to sway at the sound of his voice.

He is both beautiful and unsettling, musical and destructive, mysterious and commanding. His presence reminds us that power does not always arrive with fire and thunder. Sometimes it comes as music from nowhere, a voice in the trees, and a force that bends the natural world to its will.

Amdusias is the hidden orchestra of the Goetia, the unseen music behind the veil, and the duke whose voice can move the forest.

From Demonologia ( August 2003 )

Amdusias (also spelled Amduscias and Amdukias) is one of the Demons of hell described in the Goetia, one of the books of the manuscript grimoire known as the Lemegeton or Lesser Key of Solomon. He is mentioned by Johann Wier in his Pseudomonarchia daemonum , and by Reginald Scot in The Discoverie of Witchcraft

In Collin de Plancy’s illustration, Amdusias is crowned to show that he is a duke of hell. He has been given a horse’s head to go with his single horn, because unicorns are usually represented in the shape of a horse. Two trumpets lie on the ground, and a third trumpet is slung over his shoulders.

From “The Goetia: The Lesser Key of Solomon the King” (1904) Written by S.L. MacGregor Mathers

AMDUSIAS, or AMDUKIAS. – The Sixty-seventh Spirit is Amdusias, or Amdukias.
He is a Duke Great and Strong, appearing at first like a Unicorn, but at the request of the Exorcist he standeth before him in Human Shape, causing Trumpets, and all manner of Musical Instruments to be heard, but not soon or immediately. Also he can cause Trees to bend and incline according to the Exorcist’s Will. He giveth Excellent Familiars. He governeth 29 Legions of Spirits. And his Seal is this, etc.

From the “Pseudomonarchia Daemonum” ( 1583 ) Written by Johann Weyer (Johann Wier)

Amduscias a great and a strong duke, he commeth foorth as an unicorne, when he standeth before his maister in humane shape, being commanded, he easilie bringeth to passe, that trumpets and all musicall instruments may be heard and not seene, and also that trees shall bend and incline, according to the conjurors will, he is excellent among familiars, and hath nine and twentie legions.

Original Text :

Amduscias Dux magnus and fortis: procedit ut unicornu: in humana similiter forma, quando coram magistro suo se sistit: Et si præcipiatur, efficit facile ut tubæ and symphoniæ omniaque musicorum instrumentorum genera audiantur, nec tamen conspectui appareant: ut item arbores ad exorcistæ genu se inclinent. Optimus est una cum famulis. Imperium habet vigintinovem legionum.

From the “Dictionnaire Infernal” (edition of 1863 ) Written by Jacques Auguste Simon Collin de Plancy

Amduscias governs twenty-nine legions. His true form is as a unicorn, but appears as human form when summoned. He will give concerts if commanded, and is accompanied by the sound of trumpets and other musical instruments. Trees also bend to his command.

Original Text :

Amduscias, grand-duc aux enfers. Il a la forme d’une licorne; mais lorsqu’il est évoqué, il se montre sous une figure humaine. Il donne des concerts, si on les lui commande; on entend alors, sans rien voir, le son des trompettes et des autres instruments de musique. Les arbres s’inclinent à sa voix. Il commande vingt-neuf légions.
