« Une ville carrée entourée d'une muraille
comprend une porte au milieu de chaque côté
Si tu quittes la ville par la porte nord en marchant
20 pas, tu trouveras un arbre
Si tu la quittes par la porte sud en marchant
14 pas vers le sud puis 1 775 vers l'ouest, tu
seras aligné avec le coin de la ville et l'arbre
On cherche la longueur des côtés de la ville.»
