I had also thought about the Great Library, but came to the same conclusion as Aretii - it's not immediately useful to us. I didn't think about the Oracle though, that definitely makes sense!
Seeing the surrounding terrain, I also think there's no immediate need for many of the worker techs, so I like the Stonehenge suggestion and went for the Animal Husbandry -> Pottery -> Calendar route. ...which was sped up by our warrior exploring the ruins (*after* I had founded our capital) and getting Animal Husbandry as a freebie!

And the good news is that we have horses in the second ring of Moscow!
Moscow started to build a scout, while our warrior moved south, then crossed the river and found the first city state: Helsinki, a maritime city state.
A maritime city state so close to us is nice! The problem is that a lot of other civilizations turned out to be close to it, too.
Our warrior was drawn along a clock-wise circle around our capital, guided by ruins and hills. The second ruins provided us with advanced weapons (we have a spearman now), the third with maps of our surroundings (boo!). After that, I didn't find any more ruins, as the map is crawling with AI units.
Our scout moved northwest into the tundra, simply because that was the only region left not yet scouted by other units. The only thing he found there was a barbarian encampment with two brutes on the northeastern peninsula. I fear the brute will come for us sooner or later, but our city can deal with it.
Meanwhile, Moscow started building a worker. At size 2, I set the city to max production, speeding up the worker while delaying our growth - I hate to work bad, unimproved tiles.
The worker completed exactly on turn 20, and I set Moscow tentatively to a settler, up for discussions. I think we should build a second city ASAP before the good spots get taken!
The worker already crossed the river on his way to the cows. Next turn, Moscow's culture will get us an additional hex - it will either be the cows, the sugar or the horses (Sulla would hate this!

). If it's the horses or the sugar hex, buy the cow tile immediately!
Here's the map so far:
We've already met Washington, Suleiman, Caesar, Wu, Montezuma and Bismarck. Note that we have only found one city state so far, Helsinki! This will be very interesting - will the AIs try to win over Helsinki? We also found our first natural wonder, Old Faithful.
Just when our spearman arrived at China's capital, Wu asked for open borders. I agreed, as she's relatively far away and won't be our first target, and the spear needed to cross her borders anyway.
As you can see in the lower left corner, our spearman is near a barbarian encampment. He will be safe from attack (in a forest across the river), and it's up to the next player to decide if we should attack the encampent (cross the river first - move onto the sheep hill, then attack the next turn) or simply continue scouting south along the river. Since there are grey borders of another city state visible behind the camp, I think move around the river and then attack.
