Genoa found Dorino no less useful as a diplomatist than as an ally, for the lord of Lesbos and Foglia Vecchia had married his daughter Maria to Alexander, second son of Alexios IV, Emperor of Trebizond, in whose dominions the Genoese, owing to their Black Sea colonies, had important commercial interests, latterly greatly injured by the pro-Venetian policy of that sovereign. According to the Trapezuntine practice, Alexios had raised his eldest son John IV to the Imperial dignity in his own lifetime; but his unfilial heir conspired against him, was driven into exile, and replaced by his next brother Alexander. John IV was, however, as favourable to the Genoese as his father to the Venetians, and was restored with the assistance of a Genoese of Caffa. Alexios IV was murdered in 1429; but John IV was not allowed to reign undisturbed. His brother Alexander fled to Constantinople, where his sister was wife of the Emperor John VI, and contracted a marriage with Dorino’s daughter, in order that he might secure his support, and through him, that of Genoa, against the Emperor of Trebizond. When the Spanish traveller, Pero Tafur, visited Lesbos at this time he found Alexander there engaged in levying a fleet for his restoration. This did not, however, suit Genoese policy, and accordingly the Doge of Genoa requested Dorino in 1438 to act as peacemaker between the two brothers and to invite his son-in-law to reside at Constantinople or in Lesbos on an annuity chargeable on the revenues of Trebizond[588]. Another matrimonial alliance brought Dorino’s family into renewed relations with the Palaiologoi. In 1440, an old link between the two families had been snapped by the death of Eugenia Gattilusio, widow of the Emperor John VI’s cousin and namesake[589]—an event which was doubtless the occasion when the castle of Kokkinos on the coast of Lemnos, which had been her widow’s portion, passed into the hands of Dorino[590]. On July 27 of the following year, however, the Emperor’s brother, the Despot Constantine, afterwards the last Christian ruler of Byzantium, married Dorino’s daughter Caterina, a marriage arranged by the historian Phrantzes. This union did not last long; after a brief honeymoon in Lesbos, Constantine left his bride in her father’s care, and set out, accompanied by a Lesbian galley, for the Morea, nor did he see her again till his return in the following July. At Lesbos he took her on board his ship; but, when he reached Lemnos on his way to Constantinople, he had to take refuge behind the walls of Kokkinos from the attacks of a Turkish fleet. The Turks in vain besieged the castle of the Gattilusj for 27 days, and the strain and anxiety of the siege caused the death of his wife, which occurred at Palaiokastro in August. There the ill-fated second consort of the last hero of the Byzantine Empire was laid to rest[591].
Meanwhile, besides the acquisition of Kokkinos, thus courageously saved by his heroic son-in-law, Dorino had received from the Greek Empire the island of Thasos, which more than a century before had belonged to the Genoese family of Zaccaria. Indeed, if we may accept the two allusions to the Gattilusj in the Greek version of Bondelmonti[592] as the work of that traveller, Thasos, which was Byzantine in September, 1414, had been given to Jacopo as a fief before 1420. At any rate, a Thasian inscription of April 1, 1434, now preserved in the wall of the church of St Athanasios at Kastro, informs us that a tower was built there by Oberto de’ Grimaldi[593] a member of the well-known Ligurian family who is mentioned elsewhere[594] as a captain in the service of Dorino. Ten years later, the archæologist, Cyriacus of Ancona, upon visiting Thasos, found that Dorino had recently bestowed the island upon his son, Francesco III, who was still under the control of a preceptor, Francesco Pedemontano.
The indefatigable antiquary may have paid an earlier visit to Lesbos in 1431, but the accounts which he has left of the Gattilusj, their dominions, and the neighbouring islands of the Thracian Sea range from 1444 to 1447. In Lesbos he was well received by Dorino, who promised to aid him in exploring the whole island. He had, indeed, arrived at a fortunate moment, for the rumour of a threatened Turkish invasion had ceased, so that the lord of Lesbos had leisure for archæology, and his visitor could examine “the remains of the temple of Diana,” and “the baths of Jove,” whose name was carved in the midst of them[595]. With Dorino’s captain, Oberto de’ Grimaldi, he sailed to Foglia Vecchia, where the Gattilusj had a factory, as at Lesbos, for the production of alum, and made the acquaintance of “the Master Kanaboutzes,” probably the author of the commentary on Dionysios, who could tell him all about the Foglie, of which he was a native[596]. In Thasos, the third domain of the elder branch of the Gattilusj, he spent Christmas day, and composed a long Latin inscription as well as an Italian poem in honour of young Francesco. The enthusiastic guest prayed that the beginning of his host’s rule over Thasos might be of as good omen as “the yule log thrown on the fire in the turreted castle”; that the yoke of the barbarian Turks might be removed from Thrace, that the former dependencies of the island there might return to his sway, and that Francesco’s patron saint, St John the Evangelist, might protect this “native offspring of the Palaiologoi, this pride of the most noble Gatalusian race.” “What Thasian nymph,” he asks, “could have deprived Lesbos of her Francesco?” The attraction was the lordship of an island, which had been described by Bondelmonti as well-peopled, very fertile and containing three fair towns. Francesco had, indeed, begun well by restoring the principal city, thus earning a dedicatory inscription by the Thasian citizens and colonists, and by erecting at the entrance of the harbour some fine marble statues, which an ancient inscription showed to have represented the members of the Thasian council. At this time the island could boast of six other towns beside its “marble city,” whose walls attracted the admiration of the traveller. Under the guidance of Carlo de’ Grimaldi and “the learned Giovanni of Novara,” he inspected the numerous ancient tombs outside, the large amphitheatre with no less than 20 rows then standing intact, and the akropolis of the city[597].
The worthy Cyriacus was no less hospitably received by the junior branch of the Gattilusj. At Ænos he met Palamede with his two sons Giorgio and Dorino II, and was delighted to find there an old friend in the person of Cristoforo Dentuto, envoy extraordinary of Genoa in the Levant. Accompanied by “the prince of Ænos and Samothrace” as he calls Palamede, and by Francesco Calvi, the latter’s secretary, he was taken to see “the great tomb of Polydoros, son of Priam,” some five stadia beyond the walls, admired the sculptured figures of fauns and animals there, and copied an ancient Greek inscription from the marble base of a statue that stood before “the prince’s court.” Letters of introduction from Palamede and Francesco of Thasos secured for him a warm reception at the monastery of Hagia Laura on Mount Athos[598]. At Samothrace, Joannes Laskaris Rhyndakenos, Palamede’s prefect of the island, personally conducted the antiquary to the old city, where he saw “ancient walls and the remains of a marble temple of Neptune” (known to modern archæologists as “the Dorian marble temple”), “fragments of huge columns, epistylia and bases, and doorposts, adorned with the crowned heads of bulls and other figures”—now identified with the remains of a round building built by Arsinöe, daughter of Ptolemy Soter. Thence he went to “the new castle, founded by Palamede” some thirteen years before, and built to protect his new town of “Capsulum.” Close to the tower he saw to his delight “several ancient marbles, with dances of Nymphs sculptured and inscriptions in Latin and Greek”—the two reliefs of dancing Nymphs now in the Louvre[599]. From his accounts of the neighbouring islands, we learn that Imbros, where his guide was a noble and learned Imbriote, Hermodoros Michael Kritoboulos, the historian, in 1444 was still Byzantine, and “governed for the Emperor John Palaiologos” by that same noble, Manuel Asan, of whom inscriptions have been found there, and who had lately restored two-thirds of the akropolis[600]. We find, too, that in 1447 Theodore Branas was Byzantine governor of Lemnos, where the Gattilusj as yet held only the castle of Kokkinos[601].
The visit of the antiquary of Ancona to the Gattilusj was the calm before the storm, which was so soon to burst upon them. Even while Cyriacus was their guest, the fatal battle of Varna made Murad II master of the Near East. For a few years, indeed, the Gattilusj went on marrying and giving in marriage, as if the end of their rule were not at hand. In 1444, Dorino’s daughter Ginevra married Giacomo II Crispo, Duke of the Archipelago[602]; five years later the lord of Lesbos sent the Archbishop of Mytilene, at that time the celebrated Leonardo of Chios, to Rome to obtain from the Pope a dispensation for the marriage of his eldest surviving son, Domenico, and a daughter of Palamede. As the two young people were first-cousins, Ludovico de Campo-fregoso, Palamede’s son-in-law and at that time Doge of Genoa, begged the Pope not to grant the dispensation, and as an example of the iniquity of such an alliance he instanced the case of Dorino’s firstborn (presumably Francesco III of Thasos), who had married another daughter of Palamede and had died less than six months afterwards. The Pope refused his consent, and the marriage did not take place[603].
Hitherto the Gattilusj, partly by tribute paid ever since the reign of Murad I[604], partly by tact, had managed to keep the Turks at a distance. On one occasion, when Constantinople had been threatened, the Pope had offered to pay the expenses of the Lesbian galley, if Dorino would agree to sent it thither; but the Genoese Government, while transmitting his Holiness’ offer and praising the services of the Gattilusj to Christendom, recognised their natural unwillingness to offend the Sultan and advised Dorino, if he did send aid, to pretend that he was merely protecting Genoese interests at Pera. The Greek Emperor was able to raise a loan, if he received no actual assistance, at Ænos[605]; but in 1450, at last, Lesbos was attacked. Murad despatched a large fleet under Baltaoghli, the first in the list of Turkish admirals, against the island, and his men carried off more than 3000 souls, slaughtered many cattle, destroyed the flourishing city of Kallone, and inflicted damage to the amount of more than 150,000 ducats. It was probably on this occasion that the lady of Lesbos, Orietta d’Oria, performed the prodigy of valour that won her a niche in the literary Pantheon of her native city besides the men of her father’s house. At the time of the invasion, she seems to have been in the town of Molivos, the ancient Methymna, whose inhabitants, exhausted from lack of food, were on the point of surrendering, when she appeared among them in full armour, and led them to victory against the astonished Turks. Thereupon Dorino was able to secure by a timely present and the increase of his tribute to 2000 gold pieces a renewal of the peace which he protested that he had never broken. He was, however, under no illusions as to the durability of this truce. He wrote to Genoa, asking for assistance, reminding the Republic that he was of Genoese origin and that he had often aided her to the best of his power with men, ships, and money. Unless, therefore, she could protect him, he would be reluctantly compelled to look elsewhere for help. At the same time, after the fashion of the Christian princes of the Levant on the eve of the Turkish conquest, he announced his intention of sending an expedition to obtain his rights from the Emperor John IV of Trebizond, who had also maltreated the Genoese of Caffa, and begged the Republic to receive and revictual his galleys in her Black Sea ports. This last request was granted[606].
The Turkish conquest of Constantinople, although it sounded the death-knell of the Latin states in the Levant, was of momentary benefit to the Gattilusj. They had been close relatives and good friends of the Greek Imperial family, and one of them, a certain Laudisio, had distinguished himself in the defence of the city[607]; but, when all was over, they hastened to profit by its fall. The two islands of Lemnos and Imbros, from their position near the mouth of the Dardanelles, have always possessed great strategic importance. Under the Latin Empire, Lemnos had been the fief of the Lord High Admiral, who bore the title of Grand-duke; under the Palaiologoi it had been either the appanage of an Imperial prince, or had been entrusted to the government of some great noble. So greatly was it coveted, that Alfonso V of Aragon had made it the price of his aid for the relief of Constantinople[608], while during the siege Constantine had promised it to Giustiniani, if the Turks were repulsed[609]. When the news of the disaster reached these islands, the Byzantine authorities fled on board Italian ships, while many of the inhabitants sought refuge in Chios or in the Venetian colonies. There was, however, one leading personage in Imbros, who was resolved to remain and make terms with the victors. This was Kritoboulos, the future historian of Mohammed II, who bribed the Turkish Admiral, Hamza, not to attack the islands and through his mediation managed to send representatives of the Greek church and the local nobility with a present to the Sultan’s court at Adrianople, begging him to allow them to be administered as before. It chanced that at this moment envoys of the Gattilusj were at Adrianople, for on the fall of Constantinople both Dorino and Palamede had hastened to placate and congratulate the terrible Sultan, and to crave the grant of Lemnos and Imbros. Dorino, although he was still lord of Lesbos in name and continued to sign state documents, had been bed-ridden since 1449, and his eldest surviving son, Domenico, governed as regent. Domenico and one of Palamede’s councillors were supported by the two emissaries of Kritoboulos, and the Sultan was pleased to confer Lemnos upon the lord of Lesbos, Imbros upon him of Ænos. At the same time Mohammed ordered the former to pay an annual tribute of 3000 gold pieces for Lesbos and 2325 for Lemnos; that of Imbros was assessed at 1200 gold pieces. Thus, by the irony of fate, only nine years before its annihilation, the dominion of the Gattilusj reached its greatest extent. Indeed, there was a party in Skyros also which advocated annexation to Lesbos, but there the majority wisely preferred the nearer and more powerful lion of St Mark, which waved over Eubœa[610].
The Gattilusj were now well aware that they only existed on sufferance, and they were more careful than ever not to offend their master. Domenico paid more than one visit of obeisance to the Turkish court; and when, in June, 1455, the Turkish admiral, on his way to Rhodes, anchored off Lesbos, the historian Doukas[611], the prince’s secretary, was sent on board with a handsome present of garments of silk and of woven wool six in number, 6000 pieces of silver, 20 oxen, 50 sheep, more than 800 measures of wine, 2 bushels of biscuit and one of bread, more than 1000 lbs. of cheese, and fruit without measure, as well as gifts in proportion to their rank for the members of the admiral’s staff. Under these circumstances, it was no wonder that Hamza treated the lord of Lesbos “like a brother,” and refrained from entering the harbour, for fear of alarming the islanders.
Scarcely had the Turkish fleet left, when, on June 30, 1455, Dorino I died, leaving his dominion of Lesbos, Foglia Vecchia, Thasos, and Lemnos to his eldest surviving son, Domenico, for whom the younger, Nicolò, acted as governor in the last-named island. Before a month had passed, the fleet hove in sight of Mytilene on its homeward voyage, and was invited to anchor in the harbour, where the serviceable Doukas again visited the admiral, whom he kept in good humour by a sumptuous banquet and sped on his way with a sigh of relief on the morrow. But the historian had before him a more delicate mission—that of paying the annual tribute for Lesbos and Lemnos to Mohammed II. Starting from Lesbos on August 1, he found the Sultan at Adrianople, kissed hands in token of homage and remained seated in his presence, till His Majesty’s morning meal was over. When, however, he went to hand the money to the Sultan’s ministers next day, they ingeniously asked him after the health of his master. The historian replied that he was well and sent his greeting, whereupon the Ottomans answered, that they meant the old prince. Doukas explained that Dorino had been dead 40 days, and that his successor had already been practically prince for six years, during which time he had once or twice come in person to do homage and congratulate the Great Turk. The ministers thereupon cut short the conversation with the remark that no one had the right to assume the title of lord of Lesbos (borne till his death by Dorino), until he had come and received his principality from the hands of his Most Mighty suzerain. “Go therefore,” they said, “and return with thy master; for if he come not, he knows what the future has in store for him.” The terrified envoy hastened back to Lesbos, and set out with Domenico and several leading men of both races in the island to do homage to Mohammed. The Sultan had, however, meanwhile changed his headquarters, for the plague was then ravaging Thrace, and it was not till the Lesbian deputation reached the Bulgarian village of Zlatica that they came up with him. After the usual bakshîsh to the influential Pashas, Mahmûd and Said Achmet, they were admitted to the presence, and Domenico humbly kissed the hand of his suzerain. But on the morrow a message was conveyed to Domenico, that the Sultan wished to have the island of Thasos. Argument was useless, and the island, which had belonged for some 20, or perhaps even 35, years to the Gattilusj, was ceded to Mohammed. This sacrifice only whetted the appetite of the Sultan; on the morrow a second message announced that the tribute for Lesbos would be doubled. At this Domenico plucked up courage to reply, that, if the Sultan wished to take the whole of Lesbos, it was in his power to do so; but that to pay twice the previous tribute was beyond its present ruler’s resources. At the same time, he begged the Sultan’s ministers to intervene on his behalf. They represented the facts to their master, and the latter agreed to a compromise, by which Lesbos should thenceforth pay 4000 gold pieces, instead of 3000. Then, at last they decked Domenico with a gold-embroidered robe and his companions with silken garments; the Lesbians signed the oath of allegiance and set out on their homeward journey, “thanking God, who had delivered them out of the hands of the monster.”
