Was about to say fascinating, but you beat me to the post. Baaaaaah.
But I digress.
Quite fascinating, to see that they had the means to capture a solar eclipse back then. Must've been no mean feat what with all the equipment etc required, and the long journey involved.
My inquiring mind now want to know when was the first-ever porn movie made? Should be interesting, maybe one of El Reg's staff can have a look at it? Or even @alidabbs, seeing he did a column on sex quite recently (today).
As for the question :
I wonder how many other gems like this are hidden away moldering in some dusty archive.
Sadly, we will never know.
