It was this person perhaps who persuaded the Traveller to defer no
longer the reduction to writing of his notable experiences; but in any
case it was he who wrote down those experiences at Marco's dictation; it
is he therefore to whom we owe the preservation of this record, and
possibly even that of the Traveller's very memory. This makes the Genoese
imprisonment so important an episode in Polo's biography.
To Rusticiano we shall presently recur. But let us first bring to a
conclusion what may be gathered as to the duration of Polo's imprisonment.
It does not appear whether Pope Boniface made any new effort for
accommodation between the Republics; but other Italian princes did
interpose, and Matteo Visconti, Captain-General of Milan, styling himself
Vicar-General of the Holy Roman Empire in Lombardy, was accepted as
Mediator, along with the community of Milan. Ambassadors from both States
presented themselves at that city, and on the 25th May, 1299, they signed
the terms of a Peace.
These terms were perfectly honourable to Venice, being absolutely equal
and reciprocal; from which one is apt to conclude that the damage to the
City of the Sea was rather to her pride than to her power; the success of
Genoa, in fact, having been followed up by no systematic attack upon
Venetian commerce.[27] Among the terms was the mutual release of prisoners
on a day to be fixed by Visconti after the completion of all formalities.
This day is not recorded, but as the Treaty was ratified by the Doge of
Venice on the 1st July, and the latest extant document connected with the
formalities appears to be dated 18th July, we may believe that before the
end of August Marco Polo was restored to the family mansion in S. Giovanni
Grisostomo.
