The early part of Pytheas' voyage was outlined by statements of Eratosthenes that Strabo said are false because taken from Pytheas. Apparently, Pytheas said that tides ended at the "sacred promontory" ("Hieron akrōtērion", or Sagres Point), and from there to Gades is said to be 5 days' sail. Strabo complained about this distance, and about Pytheas' portrayal of the exact location of Tartessos. Mention of these places in a journal of the voyage indicates that Pytheas passed through the Straits of Gibraltar and sailed north along the coast of Portugal.
