The programme was about the origin myths for the Greek Gods (the pantheon in general), and about the origins of those myths themselves. Lane Fox visited several places ranging from the Near East to Italy, looking both at the places the Greeks thought their myths had taken place in and at the evidence for where the myths had come from & how old they were. He showed us that the myths in their Greek form probably originated with the Euboeans, a culture living on one of the Greek islands (Euboea, in fact) in the Greek Dark Age, pre-Classical pre-literate Greeks. They had settlements on the Turkish coast, and Lane Fox told us the myths that the Hittites who already lived there had - which were very similar to the Greek myths about Chronos overthrowing & castrating Father Heaven, then in turn being overthrown by his son Zeus.
It was a good programme, well worth watching. With lots of archaeology, telling of bloodthirsty stories & dramatic scenery to illustrate it :)
