Proof of Ancient Iranian Astrology in Zend-Avesta and Zoroaster.

Here is the conversation of Ahuramazda with Zoroaster.

The spirit of wisdom answered (4) thus: ‘The treasure of the worldly existence was a allotted as truly, in the original creation, as that of the spiritual existence. 5. And the creator, Ohrmazd, provided the happiness of every kind, that is in these creatures and creation, for the use (bun) of the sun and moon and those twelve constellations which are called the twelve chieftains by revelation; (6) and they, too, accepted it in order to allot it truly and deservedly.

  1. ‘And, afterwards, Ahriman produced those seven planets, such as are called the seven chieftains of Ahriman, for dissipating and carrying off that happiness from the creatures of Ohrmazd, in opposition to the sun and moon and those twelve constellations. 8. And as to every happiness which those constellations bestow on the creatures of Ohrmazd, (9) those planets take away as much of it as it is possible for them (the constellations) to give, (10) and give it up to the power of the demons and fiends and the bad.
