Women, how they do haunt this tale. When I began writing Arthur’s story I thought it would be a tale of men; a chronicle of swords and spears, of battles won and frontiers made, of ruined treaties and broken kings, for is that not how history itself is told? When we recite the genealogy of our kings we do not name their mothers and grandmothers, but say Mordred ap Mordred ap Uther ap Kustennin ap Kynnar and so on all the way back to the great Beli Mawr who is the father of us all. History is a story told by men and of men’s making, but in this tale of Arthur, like the glimmer of salmon in peat-dark water, the women do shine.

Men do make history, and I cannot deny that it was men who brought Britain low. There were hundreds of us, and all of us were armed in leather and iron, and hung with shield and sword and spear, and we thought Britain lay at our command for we were warriors, but it took both a man and a woman to bring Britain low, and of the two it was the woman who did the greater damage. She made one curse and an army died, and this is her tale now for she was Arthur’s enemy.

‘Who?’ Igraine will demand when she reads this.

Igraine is my Queen. She is pregnant, a thing that gives us all great joy. Her husband is King Brochvael of Powys, and I now live under his protection in the small monastery of Dinnewrac where I write Arthur’s story. I write at the command of Queen Igraine, who is too young to have known the Emperor. That is what we called Arthur, the Emperor, Amherawdr in the British tongue, though Arthur himself rarely used the title. I write in the Saxon tongue, for I am a Saxon, and because Bishop Sansum, the saint who rules our small community at Dinnewrac, would never allow me to write Arthur’s tale. Sansum hates Arthur, reviles his memory and calls him traitor, and so Igraine and I have told the saint that I am writing a gospel of our Lord Jesus Christ in the Saxon tongue and, because Sansum neither speaks Saxon nor can read any language, the deception has seen the tale safe this far.
