Nomen eius, id est Antonini, erasum est senatu iubente remansitque Varii Heliogabali, si quidem illud adfectato retinuerat, cum vult videri filius Antonini. appellatus est post mortem Tiberinus et Tractaticius et Impurus et multa, si quando ea erant designanda quae sub eo facta videbantur. solusque omnium principum et tractus est et in cloacam missus et in Tiberim praecipitatus. quod odio communi omnium contigit, a quo speciatim cavere debent imperatores, si quidem nec sepulchra mereantur qui amorem senatus populi ac militum non merentur.
(Historia Augusta, Vita Heliogabali 17.4-7)
His name, that is to say the name Antoninus, was erased from the public records by order of the senate – though the name Varius Elagabalus was left -, for he had used the name Antoninus without valid claim, wishing to be thought the son of Antoninus. After his death he was dubbed the Tiberine, the Dragged, the Filthy, and many other such names, all of which were to signify what seemed to have been done during his rule. And he was the only one of all the emperors whose body was dragged through the streets, thrust into a sewer, and hurled into the Tiber. This befell him as the result of the general hatred of all, against which particularly emperors must be on their guard, since those who do not win the love of the senate, the people, and the soldiers do not win the right of burial.
