The use of these 2½° divisions to calculate the dodekatamoria is reported to be a development of Hindu atrology, (where each partition is called a 'dwadasamsa' or 'dwad'), although reference to their use in measuring the dodekatamoria is found in the 39th chapter of Porphyry's Introduction to the Tetrabiblos. Porphyry does not explain their use in interpretation, but in regard to their calculation he tells us:

The dodecatemory of the Moon is taken properly, first by looking at how many degrees of the sign the Moon has, of that [number] measure off 2½ degrees [through] the succeeding [signs], and wherever the number leaves off, there is the dodecatemory. For example, let the Moon have 13 [degrees] of Aries: give to Aries 2½, to Taurus 2½, [to Gemini 2½,] to Cancer 2½, to Leo 2½, then the dodecatemory is in Virgo, the domicile of Mercury. The dodecatemory of the Sun is taken similarly...
