And this geometrical proportion has a place, for the transport of those holy abodes, whose differences are indicated by the differences of the numbers set down below.
And the numbers introduced are six-fold, as three hundred is six times fifty; and ten-fold, as three hundred is ten times thirty; and containing one and two-thirds (ἐπιδίμοιπροι), for fifty is one and two-thirds of thirty.
