The second programme was about Ethiopia, which I'm ashamed to say I knew nothing about before. Except that it had had an appalling famine years ago when I was a kid. So I didn't even know it had been a Christian country long before the European missionaries got there - infact they drove out the Jesuit missionaries because they preferred their own Orthodox ritual, thanks very much. Their legends are that they have had a continuous kingdom of Ethiopia for 3000 years, started by the son of Solomon & the Queen of Sheba who apparently brought the Ark of the Covenant to Ethiopia when he set up his kingdom. So first they were Jewish for a thousand years or so, then they became Christian. This programme worked its way back into the past looking at sites from various bits of history - including some awesome churches carved from solid rock, a monastery that still follows old traditions and worships in a 6thC AD church, and the ruins of a temple from ~500BC. There definitely seems to've been a continuous culture there, although the programme didn't seem to me to show enough evidence for the Jewish past (and none at all for the Solomon & Queen of Sheba). But certainly I now know significantly more about Ethiopia!
Overall I liked the programmes. My only quibble really is that there seemed to be a fair chunk of padding for each one, I'd rather've seen more things or learnt more about the things, rather than watch the presenter wrestle with a modern day "Nubian" or try his hand at plowing with an ox drawn plow. And he didn't half get carried away with the "ooooh it could really be true that ...", but the wild speculation was always clearly indicated so that's OK, and it's probably just my tastes that wanted more detail in the evidence for things rather than just the spectacle ;) And I definitely learnt stuff :)
