She smiled to herself when she thought that. Nanny knew all the old, dark stuff – old magic, magic that didn’t need witches, magic that was built into people and the landscape. It concerned things like death, and marriage, and betrothals. And promises that were promises even if there was no one to hear them. And all those things that make people touch wood and never, ever walk under a black cat.

You didn’t need to be a witch to understand it. The world around you became more – well, more real and fluid, at those special times. Nanny Ogg called it numinous – an uncharacteristically solemn word from a woman who was much more likely to be saying, ‘I would like a brandy, thank you very much, and could you make it a double while you are about it.’ And she had told Tiffany about the old days, when it seemed that witches had a bit more fun. The things that you did around the changing of the seasons, for example; all the customs that were now dead except in folk memory which, Nanny Ogg said, is deep and dark and breathing and never fades. Little rituals.

Tiffany especially liked the one about the fire. Tiffany liked fire. It was her favourite element. It was considered so powerful, and so scary to the powers of darkness that people would even get married by jumping over a fire together⁴. Apparently it helped if you said a little chant, according to Nanny Ogg, who lost no time in telling Tiffany the words, which immediately stuck in Tiffany’s mind; a lot of what Nanny Ogg told you tended to be sticky.

But those were times gone by. Everybody was more respectable now, apart from Nanny Ogg and the giant.

There were other carvings on the Chalk lands too. One of them was a white horse that Tiffany thought had once broken its way out of the ground and galloped to her rescue. Now she wondered what would happen if the giant did the same thing, because it would be very hard to find a pair of pants sixty feet long in a hurry. And on the whole, you’d want to hurry.
