Symplegades

The Symplegades (; Greek: Συμπληγάδες, Symplēgádes) or Clashing Rocks, also known as the Cyanean Rocks, were, according to Greek mythology, a pair of rocks at the Bosphorus that clashed together whenever a vessel went through. They were defeated by Jason and the Argonauts, who would have been lost and killed by the rocks except for Phineus' advice. Jason let a dove fly between the rocks to see exactly how fast they'd have to row to beat the rocks; the dove lost only its tail feathers. The Argonauts rowed mightily to get through and lost only part of the stern ornament. After that, the Symplegades stopped moving permanently. The European rock is usually identified with an islet, about 20 metres (66 ft) wide and 200 metres (660 ft) long, which stands about 100 metres (330 ft) off the shore of a village called Rumelifeneri ('Lighthouse of Rumeli’), and is connected to it by a modern concrete jetty.
