Marcus Manilius was a Latin poet and astrologer, whose biographical events are largely unknown. It is precisely his work to provide clues to the period he lived, (in book I, for example, the battle of Teutoburg is mentioned). In fact, it is believed that it was written between 10 and 20 AD. about, under Augustus and Tiberius. Astronomics is a Latin didactic poem of a stoic nature on astrology that has Lucretius's "De rerum natura" as a structural model. It is written in hexameters and divided into five books of which only the first is relevant to the title dealing with cosmology and cosmogony. This is the first extensive work on astrology and has the merit of having translated astronomical, astrological concepts and complex mathematical calculations into poetry. Many modern astrologers refer to the "Astronomica" poem in their horoscopes.
