'Bakırçay' (ancient name: ''Caicus'' also ''Caïcus'' (
Greek: 'Καϊκος' or 'Καϊκός',
transliterated as 'Kaïkos', formerly 'Astraeus' or 'Astræus') is the ancient name of a river of
Asia Minor that rises in the
Temnus mountains and flows through
Lydia,
Mysia, and
Aeolis before it
debouches into the
Elaeatic Gulf. (
Herodotus vi. 28; vii. 42).
[1]
The
Hittites called it the Seha river.
The modern,
Turkish name of the river is 'Bakırçay' (formerly the 'Ak-su', 'Aksou', and 'Bakır'), and it is located in the
Asian part of
Turkey.
The river is first mentioned by
Hesiod (''Theog.'' 343), who, as well as the other poets, fixes the quantity of the penultimate syllable.
Plutarch relates that the name of the river was originally Astraeus (Astræus) but was changed after
Caicus, a son of
Hermes, threw himself into it.
[2]
Strabo (p. 616) says that the sources of the Caicus are in a plain, which plain is separated by the range of Temnus from the plain of
Apiae (Apia), and that the plain of Apia lies above the plain of Thebe in the interior. He adds, there also flows from Tetanus a river
Mysius, which joins the Caicus below its source. The Caicus enters the sea approximately 12 km from
Pitane, and 3 km from
Elaea (Elæa). Elaea was the port of
Pergamon, which was on the Caicus, approximately 25 km from Elaea. (Strab. p. 615.) At the source of the Caicus, according to Strabo, was a place called
Gergitha.
The course of this river has undoubtedly changed since antiquity; nor is it easy to assign the proper ancient names to the branches in the ordinary maps.
Leake (''Asia Minor'', p. 269) infers from the direction of
L. Scipio's march (Liv. xxxvii. 37) from
Troy to the
Hyrcanian plain, that the north-eastern branch of the river of Pergamon (Bergama or Beryma) which flows by
Menduria (possibly Gergitha) and
Balıkesir (Caesaraea) is that which was anciently called Caicus; and he makes the Mysius join it on the right bank. The Caicus as it seems is formed by two streams which meet between 50 and 65 km above its mouth, and it drains an extensive and fertile country.
