Greek divination is divination, which is a type of magic, as performed historically in ancient Greek culture.
Within ancient Greece practice of divination, there were two groups who functioned differently in the aspect of the first being official divinaters, known as oracles, and the second, being independent divinaters.
Oracles were individuals committed to and capable of practice.
Amongst a number of others, there were oracles at Delphi and Dodona, although Greek divination had less of an institutional facet.
Of all oracles of ancient Hellenic culture and society, a man named Tiresias was thought as the most vital and important.
Zeus was known as Zeus Moiragetes, which is to refer to the power of Zeus to know the fate of mortals. The newly-born Zeus himself learnt his fate by the night and, accordingly, by Phanes, while within a dark cave.
Herodotus stated the earliest oracle was the oracle of Zeus located at Dodona, although archaeological remains at Delphi date to earlier. There was an oracle at Dodona from the 5th century BCE, although the oracle of Zeus might have still have had a practice at the same locus earlier, prior to construction of the temple, a possibility which seems probable since the temple remains show an oak tree at the location.
Apollo transfers to Hermes a skill in divination, which is divination by mantic dice. which Hermes didn't request but still was given. Speaking within the hymn, Apollo expounds on the difficulty he experiences with his own divination, and then proceeds to provide the gift of divination to his brother, Hermes, though a lesser skill, because the mantic dice are not under the control and influence of the will of Zeus. Hermes' skill at divination, though inferior to the skill of Apollo, is still of a divine nature.
The gift of Apollo is bee maidens with oracular abilities.
Apollo is next to and most closely associated with the supreme knowledge of future events which is the possession of Zeus. Apollo was known as Apollo Moiragetes which is to refer to Apollo as the god of fate. The oracle at Delphi gave oracles from Apollo.
