A couple of nights ago I listened to an interesting talk about the Mabinogion and the night sky, by the astronomer Martin Griffiths (pictured). We stood in a garden before adjourning to an inflatable planetarium. It was the launch of the Llangwm Literary Festival.
The Mabinogion stories were set down in Welsh in the 12th -13th centuries and form some of the earliest literature in Britain.
In astronomical terms there is nothing in the Mabiniogion that we don't know from other cultures - from Babylonia, via the Ancient Greeks onwards - but that doesn't make the stories any less rich.
Arctos, the Bear, becomes a horse and dead souls are rescued, I forget some of the details; but if you want to know the full score, he's written a book about it: Dark Land, Dark Skies.
The thing that really shocked me was when Martin asked, 'Why are there seven days in the week?'
I struggled to remember...
Of course... There are seven bright fasting moving heavenly bodies: the Sun, Moon, Mars, Mercury, Jupiter, Venus and Saturn.
