Caligastia, Planetary Prince = An (Sumerian) / Anu (Akkadian), supreme sky father
The Connection
Both are invisible supreme rulers whose presence is felt but never directly witnessed by mortals. An/Anu is the supreme sky god who rarely descends. Caligastia is the invisible Planetary Prince. Sumerian "melam" (terrifying divine splendor) maps to the mortal experience of sensing Caligastia's unseen presence.

Historical Evidence(Strong evidence)
ORACC (U. Penn): An/Anu "seems to have always been regarded as rather remote from human affairs." Paul-Alain Beaulieu describes Anu as a "figurehead" and "otiose deity." Britannica: "Although theoretically the highest god, Anu played only a small role in mythology, hymns, and cults of Mesopotamia." The "otiose deity" designation is the academic term for exactly this kind of invisible ruler.
