And here's a poem to go with the Moon - not megalithic at all LS but appropiate today ;) considering Nigel's posting paintings.....

The Harvest Moon

The flame-red moon, the harvest moon,
Rolls along the hills, gently bouncing,
A vast balloon,
Till it takes off, and sinks upward
To lie on the bottom of the sky, like a gold doubloon.
The harvest moon has come,
Booming softly through heaven, like a bassoon.
And the earth replies all night, like a deep drum.

So people can't sleep,
So they go out where elms and oak trees keep
A kneeling vigil, in a religious hush.
The harvest moon has come!

And all the moonlit cows and all the sheep
Stare up at her petrified, while she swells
Filling heaven, as if red hot, and sailing
Closer and closer like the end of the world.

Till the gold fields of stiff wheat
Cry `We are ripe, reap us!' and the rivers
Sweat from the melting hills.

And as there are probably more prints than paintings on the megalithic theme, perhaps Megalithic Pictures or some such would be more appropriate - could be fun :-)
