Ecce Romani universe

The Ecce Romani universe is the universe in which the Ecce Romani books are set. It appears to be extremely similar to our own, but it has a number of arguably trivial differences.

Explicit

 * The salting of Carthage happened in the Ecce Romani universe, whereas it almost certainly did not happen in ours, due to a lack of attestation from Roman sources and logistical issues.

Inferred

 * One of the reasons that the salting of Carthage probably didn't happen in our universe is that salt is quite limited in quantity. However, it did happen in the Ecce Romani universe. This may mean that salt is commoner in it than in ours.
