Louis XXIV
Le Roi Soleil
What reason do we have for believing there's "no longer gold on the map"? We know river tiles don't produce gold, but that's not a major income earner. There are still luxury resources (and undoubtedly still mints), and roads have been spotted with the trade route symbol, suggesting that you still get gold for having roads between cities.
In fact, we have seen that you still get gold from luxuries on the map. But that's still less common than all river tiles and sea tiles.
