The monomoiria is the allotment of the planets to each degree of the zodiac, distributed in the seven zoned sphere, ἑπτάζωνος σφαῖρα ("heptazonos sphaira"). This is a reference to the order of the spheres in the ancient Greek geocentric system in which there are seven concentric spheres bearing planetary bodies.

This is also known as the Chaldean Order, as derived from Macrobius. The term "Chaldean Order" does not appear in Paulus Alexandrinus. He uses the phrase, "order of the seven-zoned sphere."

After the fall of the Neo-Babylonian empire, the Greeks and Romans used the title Chaldean to designate the Babylonian soothsayers, astrologers, diviners, incantation priests and scholars.

This order lists the bodies furthest from Earth first, nearest to Earth last. To the ancient geocentric viewer, it followed the natural increasing orbital motion with Saturn as the slowest, and the Moon as the fastest:

Saturn, Jupiter, Mars, Sun, Venus, Mercury, and the Moon.
When considering the Whole Sign house system, each sign is divided into 30 degrees; after the seventh degree in the table, the cycle continues to repeat as far as it can until the thirtieth degree. The first degree for each sign in the monomoiria table is ruled by the planet which rules that sign. This is the form of monomoiria in the works of Vettius Valens, recorded by Paulus Alexandrinus, and depicted below:
