The tornado that is forming is also nice.
Concerning the little temple, I tought (and still think) that villagers can pray there to get favor. But relics have to be stored in large temple as well as myth techs are researched in large temples. As temple might be expensive for the first age, a greek player might just build one of this cheaper small temple to start gathering favor early. In addition, if really cheap, you can have many of these in various locations so that you have many options when you decide to send villagers to gather favor.
I have no idea if you gather favor as fast at those small temples?? By the way, I believe thay are called sanctuary and not temple.
