1. Story
2. The empire's actual transport network. Bulk goods - grain, oil, wine, stone, amphorae - moved by ship because water transport was roughly an order of magnitude cheaper than road haulage per tonne-kilometre in the ancient world. Rome is the only empire in the region to have held every shore of this sea at once, and once it did, the sea stopped being a frontier and became an interior. The roads are best understood as feeders to and between ports, not as an alternative to them.

20. Network models place total Roman road length between roughly 80,000 km (major viae only) and c. 192,861 km across c. 7,154 modelled segments at the empire's peak, depending on inclusion criteria. A 2025 mapping effort reported that the exact course of only about 2.7% of the network is known with certainty.
21. Empire-wide population at the mid-2nd century CE is estimated in a range of roughly 59-72 million, with the wider scholarly spread running from c. 46 million under Augustus (Frier) to 60-90 million at the high end. The familiar '60 million' is one point inside a contested range, not a measured figure; the underlying Italian census debate (low count vs high count) is unresolved.
