Marcus made me a visit two days afterwards, and supplied me with some necessaries, exhorting me, as on the part of his sovereign, to keep a good heart.  I returned his visit next day; and being very desirous to return home to Venice, I requested him to introduce me to the grand duke, which he promised to do as soon as possible, and I soon afterwards was desired to go to court.  Immediately on my getting there, I was conducted to an audience; on which I made my obeisance in due form to the grand duke, to whom I returned thanks for all the attentions I had received from his ambassador, Marcus, in the course of my journey, by whose assistance and advice I had escaped a thousand dangers; assuring his highness that I attributed these marks of kindness as done to the republic of Venice, whose ambassador I was, and that the republic would unquestionably evince a due sense of the obligations, to which I owed my life and safety.  The grand duke interrupted my harangue, by complaining with much emotion of the conduct of John Baptista of Treviso, and said a great deal on this subject, which is not proper for me to report.  After a conversation of some length, in which I spoke to his highness about my departure, he closed my audience, postponing his answers to my requests to a future opportunity.  The grand duke was very shortly to quit Moscow, on purpose to visit several parts of his dominions, and particularly the Tartar frontier, where one of his officers was stationed, with the command of 500 horse[4], to repress the incursions of robbers on that side:  I therefore endeavoured to procure an answer about my departure, and solicited a second audience for that purpose.  On this occasion I was very politely received by the grand duke, accompanied by three of his principal barons.  At first they expatiated at some length on the subject of John Baptista, formerly mentioned; but at length I received liberty to remain or to depart as I thought proper.  They dismissed me with this vague answer, and the grand duke set out from Moscow soon afterwards.  I owed a great deal of money to Marcus, which he had expended for me and my people, as he had defrayed the whole expences of our journey, and had supplied me with many things of which I stood in need.  I requested permission from him to go away, giving him the most solemn assurance that I would transmit full payment to him immediately after my arrival at Venice.  But he declared this was not in his power, as he was under the necessity of repaying the Tartarian and Russian merchants, who had advanced all these things for us, and to whom he had become security for payment.  Finding every application to the duke and Marcus on this subject ineffectual, as I could not procure the necessary funds for my journey from either, I was under the necessity of sending Stephen Testa to Venice, to solicit a remittance from our illustrious senate, by which I might be enabled to pay my debts.  Stephen left Moscow on the 7th of October, accompanied by one Nicolas Leopolitain[5], who knew the country.
