In this case we have Harmony in the repetition of a certain relation of directions (angles of divergence). In these cases, [Fig. 9] and [Fig. 10], there is Harmony also, in the repetition of a certain relation of intervals.
23. Two or more positions may lie at the same distance from a given point taken as a premise-point. In that case the positions, having a certain distance in common, are, to that extent, in Harmony.
Fig. 11
This is an example of Distance-Harmony. All the points are equally distant from the premise-point “A.” The directions vary.
We may have Distance-Harmony, also, in the repetition of a certain relation of distances.
Fig. 12
This is an illustration of what I have just described. The Harmony is of a certain relation of distances repeated.
24. Intervals, that is to say intermediate spaces, are in Harmony when they have the same measure.
