Some were founded on pure simple geometry. Others reveled in complication and it was a sort of riddle whether there was any rule governing their forms. Still others were depictions of actual people who had lived and thought interesting things at one time or another-or, barring that, of general types: the Deolater, the Physiologer, the Burger and the Sline. If someone had asked, I might have been able to explain a quarter of them. One day I’d be able to explain them all.

Sunlight crashed into the Cloister garden, where grass and gravel paths were interwoven among stands of herbs, shrubs, and the occasional tree. I reached back over my shoulder, caught the selvage end of my bolt, and drew it up over my head. I tugged down on the half of the bolt that hung below my chord, so that its fraying edge swept the ground and covered my feet. I thrust my hands together in the folds at my waist, just above the chord, and stepped out onto the grass. This was pale green and prickly, as the weather had been hot. As I came out into the open, I looked to the south dial of the clock. Ten minutes to go.

“Fraa Lio,” I said, “I do not think that slashberry is among the One Hundred and Sixty-four.” Meaning the list of plants that were allowed to be cultivated under the Second New Revised Book of Discipline.

Lio was stockier than I. When younger he had been chubby, but now he was just solid. On a patch of disturbed earth in the shade of an apple tree, he was squatting, hypnotized by the dirt. He had wrapped the selvage end of his bolt around his waist and between his thighs in the basic modesty knot. The remainder he had rolled up into a tight cylinder which he had tied at each end with his chord and then slung diagonally on his back, like a bedroll. He had invented this wrap. No one else had followed his lead. I had to admit that it looked comfortable, if stupid, on a warm day. His bottom was ten inches off the ground: he had made his sphere about the size of his head, and was balancing on it.
