As her explorations took her outward from the village, so they also took her upward. The first of the Seven Hills which Potitia conquered was the one directly behind her family’s hut. On the side that faced the settlement, the hill presented a sheer cliff that was impossible for even the most determined child to climb, but on the far side of the hill, by trial and error, Potitia discovered a route that led all the way to the top. The view was astounding. Circling the crest of the summit she could look down on the marshy lake, on the settlement below, and on the region of the hot springs, which she now could see were situated at the edge of a large plain that lay in an elbow of the Tiber. Gazing beyond these familiar places, she realized that the world was much vaster than she had previously imagined. The river stretched on in either direction for as far as she could see. Wherever she looked, the impossibly distant horizon faded to a smudge of purple.

One by one, Potitia conquered all the Seven Hills. Most of them were bigger than the one closest to home, but were easier to climb, once you knew the best place to begin the ascent and which route to take. Each hill had something to distinguish it. One was covered with a beech forest, another was crowned with a ring of ancient oaks, another was populated by osier trees, and so on. The hills had not yet been given individual names. Collectively, for longer than anyone could remember, men called them the Seven Hills. More recently, a visitor passing through had jokingly referred to the region as the ruma, which was the same word men used to refer to a woman’s breasts, or the teats of a cow, and now, as often as not, ruma was the word people used for the hilly region. To the settlers, it seemed perfectly natural to liken the features of the earth to the parts of a body.

In a cliff directly across from the settlement, beyond the meadow on the far side of the Spinon, Potitia had discovered the cave.
