Thanks for the comments!
1. There is more than one Roman, so I used the genitive plural. Is this wrong?
2. That's a very good point about using "fourth" vs. "four"--gotta love those little goofs
Also, I'm aware of missing some of the macrons. I just put in that I thought were most important, but I realize it's important to get in the habit of knowing where they all are. Maybe I should think of them as a necessary part of spelling...
