The increased importance of Chios at this period is evidenced by the coins, which the two brothers minted for their use, sometimes with the diplomatic legend, “servants of the Emperor[474].” Benedetto II was, however, eclipsed by the greater glories of Martino. By marriage the latter became baron of Damala and by purchase[475] lord of Chalandritza in the Peloponnese, and thus laid the foundations of his family’s fortunes in the principality of Achaia. He was thereby brought into close relations with the official hierarchy of the Latin Orient, from which the Zaccaria, as Genoese traders, had hitherto been excluded. Accordingly, in 1325, Philip I of Taranto, who, in virtue of his marriage with Catherine of Valois, was titular Latin Emperor of Constantinople, bestowed upon him the islands of Lesbos, Samos, Kos, and Chios, which Baldwin II had reserved for himself and his successors in the treaty of Viterbo in 1267,—a reservation repeated in 1294—together with those of Ikaria, Tenedos, Œnoussa, and Marmara, and the high-sounding title of “King and Despot of Asia Minor,” in return for his promise to furnish 500 horsemen and six galleys a year whenever the “Emperor” came into his own[476]. The practical benefits of this magnificent diploma were small—for Martino already ruled in Chios, with which Samos and Kos seem to have been united under the sway of the Zaccaria, while the other places mentioned belonged either to the Greeks or the Turks, over whom the phantom Latin Emperor had no power whatever. Indeed, this investiture by the titular ruler of Constantinople must have annoyed its actual sovereign, who had not, however, dared to refuse the renewal of the lease of Chios, when it again expired in 1319. But Martino had given hostages to fortune by his connexion with the Morea. His son, Bartolommeo, was captured by the Catalans of Athens in one of their campaigns, sent off to the custody of their patron, Frederick II of Sicily, and only released at the request of Pope John XXII in 1318. As the husband of the young Marchioness of Boudonitza, he was mixed up also in the politics of Eubœa and the mainland opposite, while he is mentioned as joining the other members of his family in their attacks upon the Turks.
