But soon there began to run through the streets and courtyards of Genoa a rumour that in prison there lay a certain Venetian captain, with tales so wonderful to beguile the passing hours that none could tire of hearing them; and anon the gallants and sages and the bold ladies of Genoa were flocking, just as the men of the Rialto had flocked before, to hear his stories of Kublai Khan.

Lord of the fruits of Tartary
  Her rivers silver-pale,
Lord of the hills of Tartary,
  Glen, thicket, wood, and dale,
Her flashing stars, her scented breeze,
Her trembling lakes, like foamless seas,
Her bird-delighting citron-trees
  In every purple vale.

‘Messer Marco,’ so runs Ramusio’s account of the tradition which lingered in Venice in his day, ’finding himself in this position, and witnessing the general eagerness to hear all about Cathay and the Great Khan, which indeed compelled him daily to repeat his story till he was weary, was advised to put the matter in writing, so he found means to get a letter written to his father in Venice, in which he desired the latter to send those notes and memoranda which he had brought home with him.’

It happened that in prison with Marco Polo there lay a certain Pisan writer of romances, Rusticiano by name,[32] who had probably been taken prisoner before at the battle of Melaria (1284), when so many Pisan captives had been carried to Genoa, that the saying arose ’He who would see Pisa let him go to Genoa.’  Rusticiano was skilled in the writing of French, the language par excellence of romances, in which he had written versions of the Round Table Tales, and in him Marco Polo found a ready scribe, who took down the stories as he told them, in the midst of the crowd of Venetian prisoners and Genoese gentlemen, raptly drinking in all the wonders of Kublai Khan.  It was by a just instinct that, when all was written, Rusticiano prefixed to the tale that same address to the lords and gentlemen of the world, bidding them to take heed and listen, which he had been wont to set at the beginning of his tales of Tristan and Lancelot and King Arthur:  ’Ye Lords, Emperors and Kings, Dukes and Marquises, Counts, Knights and Burgesses and all ye men who desire to know the divers races of men and the diversities of the different regions of the world, take ye this book and cause it to be read, and here shall ye find the greatest marvels.’  But he adds, ’Marco Polo, a wise and learned citizen of Venice, states distinctly what things he saw and what things he heard from others, for this book will be a truthful one.’  Marco Polo’s truthful marvels were more wonderful even than the exploits of Arthur’s knights, and were possibly better suited to the respectable Rusticiano’s pen, for his only other claim to distinction in the eyes of posterity seems to be that in his abridgment of the Romance of Lancelot he entirely omits the episode (if episode it can be called) of the loves of Lancelot and Guinevere.  ‘Alas,’ remarks his French editor, ’that the copy of Lancelot which fell into the hands of poor Francesca of Rimini was not one of those expurgated by Rusticiano!’ [33]
