The Lesser Key of Solomon is one of the most famous grimoires in Western occultism. Compiled anonymously in the 17th century, it contains five books: Ars Goetia, Ars Theurgia-Goetia, Ars Paulina, Ars Almadel, and Ars Notoria. The most well-known section, the Ars Goetia, documents 72 demons that King Solomon supposedly controlled using a magical ring and seals.
This guide focuses on the demons specifically named in the Ars Goetia and mentioned in the source text. Each spirit has a unique sigil, power, and rank. If you intend to summon any of these spirits, always use a magic circle and proper ritual protections.

Ritual Safety: Using the Magic Circle

If you intend to summon any Goetic spirit:
- Draw a magic circle using chalk, salt, or flour.
- Include protective symbols like pentacles, runes, or crosses.
- Use incense to protect yourself and attract the demon.
- Never rely solely on visualization—physical ritual is essential.
The magic circle is not a sign of fear, but a fortress of focus, discipline, and protection.
