Beelzebub

The name Baʿal-zəḇūḇ appears in the Books of Kings as the title of a deity worshipped in the Philistine city of Ekron. In the Hebrew/Jewish polemical context the form was treated derisively — commonly glossed as 'Lord of the Fly' — as a way of mocking a foreign Baal. In New Testament usage the name (in forms such as Beelzebul/Beelzebub) is applied to a leading adversarial spirit, the 'prince of demons,' and medieval and early modern Christian writers and occult compilers incorporated the name into hierarchies of fallen angels and infernal princes. Thus the term's history runs from a local city-Baal through polemical renaming to a theological and literary label for a high-ranking demonic power.

Primary biblical and early sources do not provide a consistent corporeal description. Later demonological summaries and folkloric listings emphasize role and attributes rather than a standardized physical form. Occult and literary treatments (e.g., the Dictionnaire Infernal and Miltonic imagery as reported in summaries) associate the name with fly/flight imagery and with a high-ranking fallen-angelic posture, but no single canonical anthropomorphic description is attested in the provided sources.

In its original context the name denotes a consulted city-deity. In New Testament passages the name functions as the label for the leader or 'prince' of hostile spirits, implying authority over demonic activity. The pseudepigraphical Testament of Solomon (as summarized) attributes to Beelzebul roles such as having once been a heavenly star-associated angel (linked to Hesperus) and causing or inspiring social and moral disorders — inciting lust among priests, jealousy, murders, war, and enabling tyrants — and inducing human worship of demons. Medieval and early modern demonologists and literary authors variably assign Beelzebub to high rank among infernal princes and connect the name with particular vices in differing taxonomies; these attributions vary by author rather than forming a uniform traditional list.
