Agrippa

In mythic genealogies preserved in classical sources and modern summaries, Agrippa is listed as a descendant of Aeneas and a king of Alba Longa, the ancient Latin city southeast of Rome; one modern summary records him as "listed as king of Alba Longa in the time of Augustus" (treated as a dynastic/ancestral figure within Rome's foundational narratives). Separately, Agrippa is a Latin praenomen/surname borne by several historical persons across the Roman and Herodian worlds (notably Marcus Vipsanius Agrippa, Agrippa Postumus, and Herod Agrippa I & II). In the early modern period the name appears as the surname of Heinrich (Henry) Cornelius Agrippa (1486–1535), an author later discussed in writings on necromancers and occult practitioners; in this reception Agrippa functions as a historical/biographical figure within the literature of Renaissance magic rather than as a unified spirit-figure.

The sources supply no consistent anthropomorphic or iconographic description that applies to a single supernatural "Agrippa." Mythic Agrippa is presented genealogically as a king of Alba Longa without descriptive adjectives. Biographical treatments of historical Agrippas (Marcus Vipsanius Agrippa, Herod Agrippa, Heinrich Cornelius Agrippa) are conventional historical or bibliographical accounts and likewise do not establish a shared physical appearance or emblematic form for an entity called "Agrippa."

No supernatural powers or behaviors are ascribed to a singular entity named Agrippa in the provided materials. In mythic context Agrippa's role is dynastic and political (as a king and descendant in foundational genealogies). Historical bearers of the name are noted for political, military, or literary activity (e.g., Marcus Vipsanius Agrippa as a Roman statesman and general). Heinrich Cornelius Agrippa is treated in later literature as an occult author associated with magical learning and, in 19th-century surveys of necromancers, included among practitioners, but the excerpts do not enumerate occult powers or present him as a supernatural being.
