Vignoso completed the conquest of Chios by the annexation of Old and New Phocæa, or Foglia Vecchia and Nuova, as the Italians called them, almost the last Byzantine possessions on the coast of Asia Minor, and celebrated for their valuable alum-mines, whence English ships used to obtain materials for dyeing, and of the neighbouring islands of Psara, or Santa Panagia, Samos, Ikaria, and the Œnoussai[486]. All these places had belonged to the former Genoese lords of Chios, with whose fortunes they were now reunited. The two Foglie, with the exception of a brief Byzantine restoration, remained in Genoese hands till they were conquered by the Turks in 1455; Foglia Vecchia, after about 1402, being administered by the Gattilusj of Lesbos, Foglia Nuova being leased to a member of the _maona_ for life or a term of years. Samos and Psara were abandoned in 1475 from fear of corsairs, and their inhabitants removed to Chios, whilst the harbourless Ikaria, where pirates could not land, was in 1362 granted to the Genoese family of Arangio, which held it with the title of Count until 1481. In that year it was ceded for greater security to the knights of Rhodes, and remained united with that island till it too was conquered by the Turks in 1522. Vignoso desired to add the rich island of Lesbos and the strategic island of Tenedos, which, as we have been lately reminded, commands the mouth of the Dardanelles, to his acquisitions. But his crews had had enough of fighting, and were so mutinous that he returned to Genoa[487].
