Get Your History On
I have mentioned this before, but now that the series is (almost) finished, I think it's a good time to bring it up again.
If you are at all interested in history (and who isn't?), I highly recommend this podcast about the Byzantine Rulers. You can find the home page here, or you can go to iTunes and search "Byzantine" or "Lars Brownsworth" to find the series "12 Byzantine Rulers."
I don't know this guy personally, but his website says that he teaches at the Stony Brook School, which is a top-tier Christian prep school on Long Island. I ran across his podcast on iTunes quite some time ago, and have found it fascinating. I highly recommend you check it out. Lars has a great way of forming history into a compelling narrative which is both informative and entertaining. I think you'll like it.
