In summary we have as follows, leaving aside here the complex and important cometary theories of the pre-socratics, Aristotle, and the Stoics. First, ca. 145-35 B.C.E. Nechepso-Petosiris wrote a book of astrology including a passage on cometary prognosis based on heavenly region of appearance. He (they?) assumed that comets were fiery (the standard theory of the era) without further ado. His view of comets seems to be that they appear in, move toward, or pause in, any quadrant of the sky. Their descriptions are irrelevant to their nature, serving only to identify them. Within the next century five further books were written. Epigenes refined the standard theory with details about whirl-winds and the like (Sen. QN 7.4-10), referred to the Chaldaians (sc. Nechepso-Petosiris?), was also an astrologer (cp. Pliny 7.160, 193), and has the simplest view of the planets (when they seem close together they are: Sen. QN 7.4.2)82). Although fundamentally Epigenes' theory is simple, it seems to have involved a detailed reworking of Aristotle's theory (Sen. QN 7.4.2-4, cp. Pliny 2.82 anonymous)83), perhaps making use of Hipparchos or of Hipparchos' Babylonian sources (note Pliny 7.193: Epigenes apud Babylonios ... obseruationes siderum coctilibus laterculis inscriptas docet). First, the three outer planets by their conjunctions generate thunder and lightning (fulgurationes being watery, fulmina containing the dry exhalation). Then the events called trabes and faces are formed from
