Peneus is a river in ancient Greek mythology, often associated with the region of Thessaly. It is known for its clear waters and is said to flow through the picturesque landscape of the Vale of Tempe. The river is often linked to the goddess Daphne, who transformed into a laurel tree to escape the advances of Apollo. In addition to its mythological significance, Peneus is also a real river in Greece, known as the Pindus River. It originates from the Pindus mountain range and flows into the Aegean Sea. The river is important for its ecological diversity and has been a vital water source for the surrounding communities.
