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.
The Twelve great gods of the Greeks were known as the Olympians. Together they presided over every aspect of human life. The goddess Hestia (listed here in the second rank) was sometimes included amongst the Twelve.
The most important of the Titan gods were the twelve Uranides (Cronus, Oceanus, Iapetus, Hyperion, Crius, Coeus, Rhea, Tethys, Theia, Phoebe, Themis and Mnemosyne) and the four Iapetionides (Atlas, Prometheus, Epimetheus and Menoetius). Of these only the eight depicted below appear in ancient art.
