Sirens are mythical creatures from ancient Greek mythology, often depicted as beautiful women with enchanting voices. They are known for luring sailors to their doom with their mesmerizing songs, causing ships to crash on rocky shores. The most famous story involving sirens is found in Homer's epic poem, the Odyssey, where the hero Odysseus must navigate past them without succumbing to their alluring melodies. In modern usage, the term "siren" can also refer to loud warning devices used in emergency situations, such as police cars, ambulances, and fire trucks. These sirens are designed to alert people to danger and ensure that emergency vehicles can navigate through traffic safely.
