He was eminently successful in his negotiations, and effected a reconciliation between Rome and Germany, and the fresco represents him kneeling humbly before the Pope and kissing his foot. On either side sits the long row of cardinals; outside we see the busy life of the Papal Court. Here Pintoricchio has brought in a rather (for him) unusual harmony in greens on the carpeting, the baldacchino, and the Pope's robes. The two figures in the foreground are said to be portraits of the Cardinals of Como and Amiens, who were both powerful friends of Æneas. The little scene through the arches on the right of the Pope brings in another episode, where the envoy receives (fresco V.) investiture as Cardinal. After this successful mission the Secretary for the first time turned his mind to the ecclesiastical life, and began to reckon on all the bright prospects it was likely to open to him. He had hitherto had the honesty to regard the license of his life as a barrier to religious orders; but his passions were growing more controllable with advancing years, and his dislike to the idea of the priesthood had passed away. He writes that he has passed from the worship of Venus to that of Bacchus, and appears to think nothing more could be required of anyone. In 1446 he received the tonsure, and was speedily named Bishop of Trieste; and three years later was appointed to the See of Siena. It was in this capacity that he was chosen to welcome to Italy Leonora of Portugal (fresco VI.), the bride of his late patron. Frederick III. was to come to Siena to meet her, and to proceed to Rome for the wedding. After some delays, Æneas received the princess on her landing at Leghorn; and on her arrival at Siena she was met by Frederick, accompanied by a splendid retinue, which included a hundred citizens "in scarlet and samite," a thousand knights under Duke Albert of Austria, the young King of Hungary, the precious relics of the city and clergy innumerable. The royal pair met outside the Camollia gate, and memoirs tell us that when the bride came in sight Frederick leapt from his horse and hastened to meet her, and that "he was rejoiced to see her so young and fair."
