The priest walks around the bottom of the pyre reading in Latin, the ritual cursing of the heretic; but I can hardly hear him above the yells of encouragement and the rumble of growing excitement from the crowd. The men with the burning torches come from the castle and walk around the pyre, lighting it all the way round the base, and then laying the torches against the wood. Someone has dampened the wood so that it will burn slowly, to give her the greatest pain, and the smoke billows around her.

I can see her lips moving, she is still looking at the upheld cross, I see that she is saying ‘Jesus, Jesus’, over and over, and for a moment I think that perhaps there will be a miracle, a storm to drown the fire, a lightning raid from the Armagnac forces. But there is nothing. Just the swirling thick smoke, and her white face, and her lips moving.

The fire is slow to catch, the crowd jeer the soldiers for laying a poor bonfire, my toes are cramped in my best shoes. The great bell starts to ring, slowly and solemnly, and though I can hardly see Joan through the thickening cloud of smoke, I recognise the turn of her head under the great paper mitre as she listens and I wonder if she is hearing her angels through the tolling of the bell, and what they are saying to her now.

The wood shifts a little and the flames start to lick. The inside of the pile is drier – they built it weeks ago for her – and now with a crackle and a blaze it is starting to brighten. Tlight makes the ramshackle buildings of the square jump and loom, the smoke swirls more quickly, the brightness of the fire throws a flickering glow on Joan and I see her look up, clearly I see her form the word ‘Jesus’, and then like a child going to sleep her head droops and she is quiet.

Childishly, I think for a moment perhaps she has gone to sleep, perhaps this is the miracle sent by God, then there is a sudden blaze as the long white robe catches fire and a tongue of flame flickers up her back and the paper mitre starts to brown and curl. She is still, silent as a little stone angel, and the pyre shifts and the bright sparks fly up.

I grit my teeth, and I find my aunt’s hand clutching mine. ‘Don’t faint,’ she hisses. ‘You have to stand up.’ We stand hand-clasped, our faces quite blank, as if this were not a nightmare that tells me, as clearly as if it were written in letters of fire, what ending a girl may expect if she defies the rules of men and thinks she can make her own destiny. I am here not only to witness what happens to a heretic. I am here to witness what happens to a woman who thinks she knows more than men.
