Rh stage of which ended at Constantinople. Beyond the imperial city, in Asia Minor, the four routes which had marked the progress of the first crusade in Europe merged into a single trail over which the motley crowd of friar, beggar and adventurer, gathered from every European nation, steered its way towards Jerusalem.

From B.C. 1250 to 1425 Black Sea coast towns constituted western termini of important caravan routes proceeding from the heart of Asia. Tabriz, the great rendezvous of traders traveling from China, India or Arabia, was connected to Trebizond by the valley of the Arax. The seaports of Samsun, Poti and Tana also received the products of Asia destined for western Europe. The bulk of this Black Sea commerce was in the hands of Venetians and Genoese. Natives of the independent cities of Italy had their agencies in every Euxine harbor of any consequence. The Eurasian waterways had permitted the establishment of Italian commercial colonies on the coast of the Black Sea. Families claiming descent from Italian medieval settlers are found to-day in many harbors of ancient or modern importance.

If abundance of nomenclature on ancient maps be considered as expression of the commercial importance of a given region the names on the Black Sea coast preserved on medieval maps suffice to reveal the extent of trade relations between Italy and the Levant. The tonnage of Italian traffic with the East was derived not only from the important agencies like that of Galata founded by the Genoese within the present limits of Constantinople, but from numerous smaller posts and colonies scattered on the Black Sea coast.

The westerly spread of the Turks resulted in the gradual closing of the eastern waterways to Christian traders. In particular the control of the Dardanelles-Bosporus sea road by the Turks in the sixteenth century destroyed the most convenient avenue of intercourse between the prosperous Italian republics and their Black Sea colonies. From this time on trade relations between north-central Mediterranean ports and the Ægean and Black seas dwindled to insignificance on account of the restriction imposed by the Turkish government and the vexations to travelers caused by its officials.

The destruction of this Levant trade, however, did not end the demand of Europe for the products which the East had hitherto supplied. Spices consisting principally of pepper, cinnamon, ginger, cloves and nutmeg were still sought. The stocks of silk, gum, lacquer and certain perfumes and precious stones were being gradually depleted. These products now reached Europe intermittently and by way of southerly routes through Asia Minor, Syria and Arabia. The journeys to which traders had to submit were long and perilous. The result was that spices sold in Italian ports three or four times higher than in Calicut. Incense could only be obtained at six times its selling price in Mecca.
