After a short visit to his friend, the Elector of Mainz, who, he said, "assured me to be assisting in all things," Rupert reached Vienna. There he was very cordially received by the Emperor, though the Spanish Ambassador, for political reasons, saw fit to ignore his arrival. The Austrians were still loth to let him leave them; and on June 22, he wrote to Legge: "A friend of mine, att my coming, assured me that there were but twoe difficulties whiche hindred my advancement to the Generallship of the Horse. The one was my being no Roman, the other that the Marquess of Baden and Generall Feldzeugmeister de Sanch might take ill if I was advanced before them. And he thought both these small impediments might easily be overcome, but especially the first, on whiche, he assured me, most ded depend." He had not yet forgotten his role of Protestant martyr! To this letter he added, as usual, a hurried and incoherent postcript. "I almost forgott to tell you how that Comte Lesley's cousin, (I forgott his name, but I remember that his sister was married to St. Michel,) this man ded me the favor to send over a booke to Comte Lesley, entitled 'The Iron Age,' in whiche it speekes most base languiage of me and my actions in England. It is dedicated to Jake Russell, {299} but I am confident if honest Jake had reade the booke, he would have broke the translator's head.... One Harris translated it; pray inquire after the booke, and juge if it were not a Scotch tricke to sende it... Moutray is the name I forgott." By July the Spanish Ambassador had deigned to visit the Prince, and to reveal the true cause of his long delay--namely, the rumours of Charles II's approaching marriage with the Infanta of Portugal, which was likely to produce a war with Spain. For this same reason, joined with their resentment at Rupert's refusal of the Generalship of the horse, the Austrian Ministers also treated him with coldness, though the personal kindness of the Imperial family was never abated. "In the meantime be pleased to knowe that Rupert is but coldly used by the Ministers here," wrote the Prince; "they would have him demand the Generallship before there is an appearance of subsistence,--nay, before what is oweing in arreare, by the Peace of Munster, be made sure unto him; to whiche Rupert doth no waies incline, especialy since he had the intimation given him that his religion was an obstacle to his advancement in the warr. The Emperor, Emperatrice and Archduc are extreamly kind to Rupert; but noen of the Counsellors have done him the honor of a visit. The reason is, I believe, the marriage aforesaid... For God's sake, if there be any likelihood of a breach with Spaine, lett us knowe it by times; it concerns us, Ile assure you."
