which is precisely on this ball opposite to Maria; and I believe that
from Rome to where this second stone would fall, going in a direct
line to the South, the distance may be seven thousand five hundred
miles, a little more or less. And here let us imagine another city,
which may have the name of Lucia; and the distance, from whatever part
one draws the line, is ten thousand two hundred miles between the one
and the other, that is, half the circumference of this ball, so that
the citizens of Maria hold the soles of the feet opposite the soles of
the feet of the citizens of Lucia. Let us imagine also a circle upon
this ball which is in every part equi-distant from Maria as from
Lucia. I believe that this circle, according to what I understand by
the assertions of the Astrologers, and by that of Albertus Magnus in
his book On the Nature of Places and on the Properties of the
Elements, and also by the testimony of Lucan in his ninth book, would
divide this Earth uncovered by the sea in the Meridian, almost through
all the extreme end of the first climate, where there are amongst the
other people the Garamanti, who are almost always naked; to whom came
Cato with the people of Rome when flying from the dominion of Cæsar.
Having marked out these three places upon this ball, one can easily
see how the Sun circles round it.

I say, then, that the Heaven of the Sun revolves from West to East,
not directly against the diurnal movement, that is, of the day and
night, but obliquely against that, so that its mid-circle, which is
equally between its Poles, in which is the body of the Sun, cuts into
two opposite parts the circle of the two first Poles, in the beginning
of Aries and in the beginning of Libra; and it is divided by two arcs
from it, one towards the North and one towards the South; the points
of these two said arcs are equi-distant from the first circle in every
part by twenty-three degrees and one point more, and the one point is
