The visions experienced by oracles in Greek practices represent divine insights or guidance. They often served as a link between the gods and humans, providing prophecies and advice on crucial decisions, wars, and personal matters. Such visions, notably from the Oracle of Delphi, were seen as manifestations of the divine will and held significant cultural and religious importance. These prophetic utterances were often cryptic, leading to various interpretations, reflecting the complex interplay between fate and free will in Greek spirituality.
