Queen Candace was a formidable woman who had mounted
an attack on Thebaid. She submitted to the prefect Petronius, and he left a Roman
Garrison at Primis. However the potential revenue from
the area did not justify the expense of maintaining a
permanent military presence and within a year or two the
limits of Roman occupation had been set at Hiera
Sykaminos, which was some eighty kilometers to the south
of the First Cataract.
