Written this second of March, from the gate of the Urbs Beata.
It was a combination of urbs in rure, which my experience had not prepared me to anticipate.
They have been understood as saying that the suburbs were two miles from their urbs.
Urbs, "city," seems here rather to designate country or territory.
For urbs and oppidum in apposition with a Locative, see 169, 4.
