The fourth volume of Divination in Ancient Greece is made up of three parts. In the part titled "Water", hydromancy and its variants and sub-variants are dealt with - which is to say, lecanomancy, eleomancy, ooscopy, alphitomancy, catoptromancy, crystallomancy, xiphomancy, onychomancy and pallamomancy.
The part titled "Air" is divided into two sections. The first comprises a corpus of techniques which are collectively bunched together into meteoromancy, that is, divinatory interpretations of comets, meteors and eclipses, selenomancy, ceraunoscopy, brontoscopy, seismomancy, anemomancy, nephomancy and predictive meteo-calendars (parapegmata).
The second section contains a thorough analysis of ornithomancy, namely its Greek and Roman variants. The concluding section is titled "Fire" and includes pyromancy, capnomancy, libanomancy, omoplatoscopy, lychnomancy, photagogy and acumenomancy.
