I'70, when it was proposed, after the capture of Phocaea and Teos in 545 B.C., that the remainder of the Ionian Greeks should emigrate to Sardinia) none of them ever came to anything.
A large part of the emigrants proceeded only as far as Chios, returned to Phocaea, and submitted to the Persian yoke.
Phocaea continued to exist under the Persian government, but greatly reduced in population and commerce.
LAMPSACUS, an ancient Greek colony in Mysia, Asia Minor, known as Pityusa or Pityussa before its colonization by Ionian Greeks from Phocaea and Miletus, was situated on the Hellespont, opposite Callipolis (Gallipoli) in Thrace.
On the Aegean coast it often occurs in early coinage (17) -- at Lampsacus 131-129, Phocaea 256-254, Cyzicus 252-247, Methymna 124.6, &c. In later times it was a main unit of North Syria, and also on the Euxine, leaden weights of Antioch,(3), Callatia and Tomis being known (38).
It was used at Phocaea as 58.5, and passed to the colonies of Posidonia and Velia as 59 or 118.
In the 8th and probably in the 9th century B.C. communication with Phrygia seems to have been maintained especially by the Greeks of Cyme, Phocaea and Smyrna.
The Little Iliad and the Phocais, according to the Herodotean life, were composed by Homer when he lived at Phocaea with a certain Thestorides, who carried them off to Chios and there gained fame by reciting them as his own.
Pherecydes (5th century) attributed to Leleges the coast land of Caria from Ephesus to Phocaea, with the islands of Samos and Chios, placing the "true Carians" farther south from Ephesus to Miletus.
The products of the island were largely exported on the ships of Miletus, with which city Chios formed a close mercantile alliance in opposition to the rival league of Phocaea and Samos.
Similar commercial considerations determined the Chians in their attitude towards the Persian conquerors: in 546 they submitted to Cyrus as eagerly as Phocaea resisted him; during the Ionian revolt their fleet of too sail joined the Milesians in offering a desperate opposition at Lade (494).
These were (from south to north) - Miletus, Myus, Priene, Ephesus, Colophon, Lebedus, Teos, Erythrae, Clazomenae and Phocaea, together with Samos and Chios.
Phocaea was one of the first Greek cities whose mariners explored the shores of the western Mediterranean.
