Symplegades

[1] The Asian rock is probably a reef off the Yum Burnu (north of Anadolu Feneri 'Lighthouse of Anatolia'), described by Gyllius: The reef is divided into four rocks above water which, however, are joined below; it is separated from the continent by a narrow channel filled with many stones, by which as by a staircase one can cross the channel with dry feet when the sea is calm; but when the sea is rough, waves surround the four rocks into which I said the reef is divided.

Lord Byron refers to the Symplegades in the concluding stanzas of Childe Harold's Pilgrimage: And from the Alban Mount we now behold Our friend of youth, that ocean, which when we Beheld it last by Calp's rock unfold Those waves, we follow on till the dark Euxine roll'd Upon the blue Symplegades ...

In his 1961 novel Jason, Henry Treece depicts the Symplegades as icebergs that drifted downriver into the Black Sea.

The Symplegades are sometimes identified with (or confused with) the Planctae (Πλαγκταί) or Wandering Rocks, which are mentioned in the Odyssey and Apollonius of Rhodes' Argonautica.

The similarities and differences between the Wandering Rocks and the Symplegades have been much debated by scholars, as have potential locations for them.
