- Abraxas — A mystical word, symbolic formula, and supreme deity in the cosmology of certain Gnostic sects (especially the followers of Basilides), representing the Supreme Divinity, the Primordial Source, or the ruler of the 365 heavens; (history of religions) a cabalistic word whose Greek letters, when added according to Hellenic numerology (isopsephy), total exactly the value of 365, corresponding to the number of days in a solar year; symbolically represented as a hybrid figure with a rooster's head, a human body, and legs formed by serpents.
- Acromancy — An ancient form of divination based on the observation and interpretation of the shapes and evolution of air, mist, or atmospheric vapors; the art of predicting the future through specific aeromantic phenomena. In its ritualistic essence, this practice involved the mystical isolation of the seer in an open space, where the patterns left by early air currents or condensed vapors were decoded as subtle messages from the divinity.
- Agrippa — The Latin and international orthographic form for the historical name Agripa. It is borne by outstanding figures of antiquity and later eras, such as Marcus Vipsanius Agrippa (Roman statesman and general), Heinrich Cornelius Agrippa von Nettesheim (Renaissance astrologer and alchemist), or the Greek skeptic philosopher Agrippa, famous for the five tropes or modes used to justify suspension of judgment.
- Amulet — A small object, often engraved, carved, or crafted from precious materials, stones, or metal, to which popular superstition or religious beliefs attribute a magical power to protect the owner against evil spirits, illnesses, and bad luck. It represents an archetypal cult element, used since antiquity as a symbolic shield worn around the neck or kept in living spaces.
