Sure.
It's currently t143, but let's go back a bit. I took some shots on t134...
As you can tell by looking at the relative positions of the purple lines, I have built up quite a strong military in the past few turns, thanks in large part to Comet Zone, which has my Heroic Epic, had some forests a few turns ago, and thus produced a unit a turn for a good while. The best part is that almost all my units have 5xp, from Vassalage.
Next, new land, discovered by my Caravels. Sadly no huts were present, so no chance of popping astronomy for free. Basically this is worth a good seafood city, and two happiness resources. It's too bad we banned war elephants; that ivory would actually be useful vs cataphracts!
Since I had counted about 40 missing land tiles and this island is 8, there are pretty clearly 5 of them (one per player).
Astronomy came in 3 turns earlier than predicted by this shot, due to a) being repayed by Lewwyn [who replaced Athlete], b) revolting back to bureaucracy for a bit, and c) borrowing some gold from Lewwyn. And that was despite running espionage slider part-time to keep Ruff and Nakor from seeing my research. I believe I was successful with that, though I admit I'm not that confident of how EP costs work.
So here is turn 140:
Galleons are already on the way, and in some cases, here! Like I said, I've played t143 already, but you're going to have to wait for t146 (IIRC) for the next update.
Meanwhile, in foreign policy...
I've been communicating extensively with Lewwyn who immediately seemed to have the right attitude (good at fighting & cooperative). I'm sure his thread is good, and I'm sure you're already reading it. My woodsman axe and workboat have been scouting out TRD's territory and forces for Lewwyn in their war, helping him know when it's safe to advance. So far he has recaptured his own city (which athlete lost the moment before he retired) and one more of TRD's, and he pretty much destroyed TRD's standing army this last turn. Barring any surprises, TRD is going to lose several more cities and be pretty much out of it from that point. As a nail in the coffin, Lewwyn will have increased mobility soon with Engineering finishing and the possibility of gifted Galleons.
Ruff is pretty much screwed, details to be presented on the turn of screwing.
Nakor is still something of an enigma, though it seems clear he wants to get Cataphracts. According to him he is planning to attack Ruff with them. As of the previous update, I had suggested a mutual defense pact to Nakor with regard to Ruff, and he did not respond to this for over a week, which I took as a sign of enmity. But more recently I asked him again and he agreed. So we now have a short-term NAP, with a few other clauses that will probably not come up. I'm happy about this because even with galleons, my mostly-mace army shouldn't really be attacking someone who has been building lots of crossbows anyway. To fight Nakor, I should really get muskets or better, ideally rifles, first.
