Calig'ula's pride first appeared in his assuming to himself the title of ruler; which was usually granted only to kings.

He would also have taken the crown and diadem, had he not been advised, that he was already superior to all the monarchs of the world.22.Not long after he assumed divine honours, and gave himself the names of such divinities as he thought most agreeable to his nature.

For this purpose he caused the heads of the statues of Jupiter, and some other gods, to be struck off, and his own to be put in their places.

He frequently seated himself between Castor and Pollux, and ordered that all who came to this temple to worship should pay their adorations only to himself.23.However, such was the extravagant inconsistency of this unaccountable idiot, that he changed his divinity as often as he changed his clothes; being at one time a male deity, at another a female; sometimes Jupiter or Mars; and not unfrequently Venus or Diana.24.He even built and dedicated a temple to his own divinity, in which his statue of gold was every day dressed in robes similar to those which he himself wore, and worshipped by crowds of adorers.
His priests were numerous; the sacrifices made to him were of the most exquisite delicacies that could be procured; and the dignity of the priesthood was sought by the most opulent men of the city.

However, he admitted his wife and his horse to that honour; and to give a finishing stroke to his absurdities, became a priest to himself.
