The superstition of Antoninus

The Sun was worshipped at Emesa, under the name of Elagabalus, and under the form of a black conical stone, which, as it was universally believed, had fallen from heaven on that sacred place. To this protecting deity, Antoninus, not without some reason, ascribed his elevation to the throne. The display of superstitious gratitude was the only serious business of his reign. [...]

Pallas had been first chosen for his comfort; but as it was dreaded lest her warlike terrors might affright the soft delicacy of a Syrian deity, the Moon, adored by the Africans under the name of Astarte, was deemed a more suitable companion for the Sun. Her image, with the rich offerings of her temple as a marriage portion was transported with solemn pomp from Carthage to Rome, and the day of these mystic nuptials was a general festival in the capital and throughout the empire.

Severus proves the exception

The true interest of an absolute monarch generally coincides with that of his people. Their numbers, their wealth, their order, and their security, are the best and only foundations of his real greatness; and were he totally devoid of virtue, prudence might supply its place, and would dictate the same rule of conduct.
