Well, after the programme I was disappointed that we had not more time to spend on the Renaissance and on the Enlightenment and the influence of Epicureanism on both those galvanic, West European, civilising turning points in our history. But we had to spend the time on the earlier stuff in order to bring out the amazing breadth and depth of Epicurean thinking. Marx, I was told afterwards, had written a dissertation on the differences in the philosophy between Epicureans and himself. It's entertaining to think of the two of them in the same room - or garden.
The last few weeks have been fast motion. I haven't even had time to chat about the Culture series, which Tom Morris and I managed to get together in autumn and put out in the very first week of this year and which gathered some tremendous comments. By the way, Epicurus - as I speak - is tweeting away, with people saying they want to be Epicureans. I wonder which bit they want to concentrate on. Then there's been filming on William Tyndale and in Israel and Palestine on Mary Magdalene - documentaries for the BBC - and embroiled in a new season of the South Bank Show and Awards.
Therefore, a few notes. I saw the pelicans being fed in St James's Park as I walked by there to the House of Lords two evenings ago. It's extraordinary to see a fish as big as a forearm being dropped into the pouch of a pelican, which then arches its neck and, without any visible sign, presumably the fish goes right down to the cistern belly of the said bird.
On Hampstead Heath, when I was walking, I saw a swan make a crash landing on the tarmac just outside one of the ponds. It stood up and, as it were, brushed itself down, pecked itself up and walked away from the scene of the crash.
In the Arab market in Jerusalem, young boys were taking incredibly overloaded carts of vegetables down steep streets and controlling the speed of these carts by stepping on an old car tyre, which was roped to the back of the cart, and leaning their weight back and slowing it down that way. The place fizzed, as it is easy to imagine that it has fizzed for more than two thousand years. Beside a washing place in the middle of one of the alleys, five women were washing their family clothes, I presume, and when we drew near with a camera, they folded their headdresses over their faces and we knocked off the cameras.
We were led to 1st-century tombs, literally carved into the rock above Jerusalem, and judging by the congestion of cobwebs, scarcely ever visited. In Bethlehem I went to a hill which overlooked the winery and the ever-extending Wall and settlements which have an air of fortresses. In both Jerusalem and Bethlehem, it was moving to see the passion of people in what they think to be the authentic shrines of the birth and death of Christ. People kissing the stone on which he was laid out and putting T-shirts and photographs on that stone, somehow to be blessed by it. It's a devotion easy to ridicule, less easy to understand, but surely important enough to think about without mockery. I was there for two Shabbats and the sight of Orthodox families in full dress - father, mother, many children - walking through the streets in the afternoon was, again, something which flicked you back hundreds of years and is visible evidence of tradition and continuity which can't fail to be moving.
The Basilica of St Anne in Jerusalem is one of the most perfect churches I have ever seen. It was the first time I'd been in it. There's a place called The Tent in Bethlehem which served the sweetest lamb I've ever tasted. It was cooked with ancient methods, in a pot with the vegetables and so on.
Back in London the sun is shining and I'm trying to make Regent's Park before I come back to the office and get on with a bit of work, and then out tonight for an Amnesty event. I'd like to walk there. London at twilight takes you straight back to Dickens and Conan Doyle, whatever the traffic.
A bit all over the place, then.
