The gods of the Greek pantheon are divided here into several categories. The first three of these--the Olympian gods, Titan gods, & primeval gods--represent the three different generations of gods to rule the cosmos. The next five categories divide the gods according to domain, namely the gods of sky, sea, earth (i.e. rustic and agricultural) and underworld. The final category contains personifications, those gods and spirits which represented abstract ideas, human emotions and conditions.
