What is "colaeus"

Colaeus was an ancient Samian explorer and silver merchant, who according to Herodotus (Hdt. 4.152) arrived at Tartessos circa 640 B.C.

In an era where most Greek traders were anonymous, Herodotus believed that Colaeus and Sostratus the Aeginetan were important enough to note. Colaeus was on a venture to Egypt when he was blown off course by a great storm through the Mediterranean and into the Atlantic by the Strait of Gibraltar as far as Tartessus, south-western Spain. Tartessus had previously been unvisited by traders and Colaeus was able to obtain a cargo of metal and return it safely to Samos. Upon his return, he dedicated one tenth of his profits to his native goddess, Hera. It is widely believed that the storm was an invention by Colaeus to hide his trade route from his competitors as the rewards from the previously untapped source of metal proved immense. Phocaeans were the first visitors of Tartessos ( Herodotus (Hdt. 1.163))Πρώτῃ δὲ Φωκαίη Ἰωνίης ἐπεχείρησε. Φωκαιέες .... καὶ τόν τε Ἀνδρίην καὶ τὴν Τυρσηνίην καὶ τὴν Ἰβηρίην καὶ τον Ταρτησσὸν οὗτοι εἰσὶν οἱ καταδέξαντες (First Ionian Phocea was involved. Phoceans… discovered Adriatic and Tyrrenean and Iberia and Tartessos. Arriving at Tartessos were welcomed by the Tartessian king by the name Argathonios (ἀπικόμενοι δὲ ἐς τὸν Ταρτησσὸν προσφιλέες ἐγένοντο τῷ βασιλεῖ τῶν Ταρτησσίων, τῷ οὔνομα μὲν ἦν Ἀργαθώνιος. Colaeus' voyage and profited enough to devote the tenth of his earnings to Hera. Phoceans build a new fortification wall for Phocaea.
