XII is inscribed at both ends.
When the needle which is governed by the magnet points directly
from the north to the south, the number XII at its tail, which is
forked, signifies the north, that number XII which is at its point indicates
the south. The sign VI superior indicates the east, and VI inferior the
west. Further, between each two cardinal points there are always
five others which are not so important. The first two of these directions
are called the prior directions; the last two are called the posterior, and
the fifth direction lies immediately between the former and the latter; it
is halved, and one half is attributed to one cardinal point and one half to the
other. For example, between the northern number XII and the eastern
number VI, are points numbered I, II, III, IV, V, of which I and
