As we might expect from so shrewd a statesman, the founder of this island-duchy was fully sensible of the advantages to be derived from having the Greeks on his side. Instead of treating them as serfs and schismatics, he allowed all those who did not intrigue against him with the Greek potentates at Trebizond, Nice, or Arta, to retain their property. He guaranteed the free exercise of their religion, nor did he allow the Catholic archbishop, sent him by the Pope, to persecute the Orthodox clergy or their flocks. The former imperial domains were confiscated, in order to provide and maintain a new fleet, so necessary to the existence of islands menaced by pirates. That Marco I was a powerful and wealthy ruler is proved not only by his buildings, but also by the value set upon his aid. When the Cretans had risen, as they so often did, against the Venetians, the Governor sent in hot haste to Naxos for Marco’s assistance. The Duke was still a citizen of the Republic; but the Governor knew his man, and stimulated his patriotism by the offer of lands in Crete. Marco lost no time in appearing upon the scene, defeated the insurgents, and claimed his reward. The Governor was also a Venetian, and not over-desirous of parting with his lands now that the danger seemed to be over. But Marco knew his Greeks by this time, and readily entered into a plot with a Cretan chief for the conquest of the island. Candia was speedily his, while the Governor had to escape in woman’s clothes to the fortress of Temenos. But, just as he seemed likely to annex Crete to his Duchy, Venetian reinforcements arrived. Unable to carry out his design, he yet succeeded by his diplomacy in securing an amnesty and pecuniary compensation, with which he retired to his island domain. But the failure of his Cretan adventure did not in the least damp his ardour. With only eight ships he boldly attacked the squadron of the Emperor of Nice, nearly four times as numerous. Captured and carried as a prisoner to the Nicene Court, he so greatly impressed the Emperor by his courage and manly beauty that the latter ordered his release, and gave him one of the princesses of the imperial house in marriage. In short, his career was that of a typical Venetian adventurer, brave, hard-headed, selfish, and unscrupulous; in fact, just the sort of man to found a dynasty in a part of the world where cleverness counts for more than heroic simplicity of character.
