About the Bosphorus
The Bosphorus is a unique and fascinating waterway that has been a vital part of Istanbul's identity for centuries. Its English name comes from a Greek legend about Zeus and Io, a beautiful woman he turned into a cow.
The Bosphorus has been a crucial waterway since ancient times, with Ulysses and Byzas sailing through it in search of the perfect place to settle. Byzas founded Byzantium, which would later become Constantinople and then Istanbul.
Geological evidence suggests that the Bosphorus was once blocked by earth and rock, but an earthquake destroyed the blockage, releasing a massive amount of water into the Black Sea. This event may have inspired the legend of Noah's flood and the story of Noah's Ark.
The Legend
The Bosphorus's English name comes from a Greek legend where Zeus had an affair with Io, a beautiful woman he turned into a cow, and she jumped across the strait.
Geological evidence suggests that in ancient times, the northern end of the Bosphorus was blocked by earth and rock, causing the Black Sea's water level to be below that of the Aegean Sea and the Sea of Marmara.
This blockage was eventually destroyed by an earthquake, releasing a massive amount of water into the Black Sea and flooding coastal communities.
The Bosphorus's name, "crossing place of the cow", is a direct result of this mythological event.
The first recorded mention of the Bosphorus dates back to the ancient Greeks in the 7th century BC, who established colonies on the European shore.
The strait's name derives from the Greek myth of Io, who swam across the waters after being transformed into a cow by Zeus.
Mount Ararat, also located in Turkey, is often associated with the legend of Noah's Ark, and it's possible that the Bosphorus is the source of Noah's flood.
