So, this quiz needed a bit of an update due to some missing cities on here. Most notably some in the short-lived eastern provinces and vassal, but also Amfipoli and Cádiz.
That's the Roman era for you. With the Germanic invasions in Europe later on, the continent would be absolutely devastated with most cities dipping way below the figures here and would not recover for centuries on end.
I am a bit surprised that Jerusalem didn't make it. Also, without a map, I would guess that some Geek and Pheonician colonies would be here (eg. Massilia/Marseille, Malaca/Malaga). And finally, it turns out that Lutetia/Paris was not as crowdy as according to Asterix :D
Jerusalem was in ruins at Roman peak territorial expansion. The city was destroyed in 70 AD after quelling a Jewish rebellion and wouldn't be restored until 130 AD.
Surprisingly those colonies were pretty sparsely populated in comparison to other cities. Massilia sitting at around 15k while Malaca was relatively small at 3k.
Lutetia was never actually that major under the Romans and would sit at approximately 8k inhabitants.
I went to Paphos in Cyprus not too long ago, which is not on this list, but was still a relative large city which was estimate to have hosted about 20,000 people at its peak.
Very impressive ruins, including lots of mosaics, houses, a theatre and even part of the old town walls.
Some new sources include:
Ancient Charax Spasinou (Iraq) - Interpreting a multi-phase city - At 700 ha, this is a very large city. It's also a relatively newly excavated site (2016). Due to this, a safer population density of 100/ha was used.
Modernization Theory and House Garden Transformation; Erbil City as Case Study - For Arbela. Approximately 125 ha in size during the second stage. A population density of 200/ha was used.
Surprisingly those colonies were pretty sparsely populated in comparison to other cities. Massilia sitting at around 15k while Malaca was relatively small at 3k.

(I've also been to Argos, but mostly just for cheap toasters and stuff.)
