the title of Emperor [781]; and, upon his quitting the province soon
afterwards, would needs have detained him, earnestly begging him, and
that not without threats, "either to stay, or take them all with him."
This occurrence gave rise to the suspicion of his being engaged in a
design to rebel against his father, and claim for himself the government
of the East; and the suspicion increased, when, on his way to Alexandria,
he wore a diadem at the consecration of the ox Apis at Memphis; and,

Making, therefore, what haste he could into Italy, he arrived first at
