She, a woman of delicate health, the widowed Queen of Bosnia, the daughter of the Duke of St. Sava, on her mother’s side[121] tracing her lineage from the imperial race of the Comneni, fled away on foot through the passes of the Dinaric Alps, down the valley of the Narenta, across the inhospitable limestone desert that stretches, now as then, between her father’s stronghold of Mostar and the sea, to Stagno, the old seaport of Bosnia. There she found a small boat, which carried her across the gulf to the hospitable haven of Ragusa. At Ragusa she seems to have resided several years; but in 1475[122] she set forth on her pilgrimage once more, and passed the closing years of her life in the shelter of a Roman convent, distinguished by her charitable works, her meekness, and the patience with which she bore her misfortunes,[123] but haunted even there by the craven conduct of her son Sigismund, who had renegaded to the creed of Mahomet. In 1477 Queen Catharine died, and was buried in the Church of the Virgin of Ara Cœli, in which by her orders a monument was reared to her memory.[124] There, beside the feudal escutcheons of her husband’s kingdom and her father’s principality, on a foreign soil, and in a Roman sanctuary, reposes, as is fitting, the effigy of the exiled Queen of Bosnia, the last monument of the feudal kingdom, and of a dynasty essentially alien to the people over whom it ruled. After her death two of her family appeared before Pope Sextus IV., and presented to him her will, in which she bequeathed her kingdom of Bosnia to the Holy Roman Church; adding, however, the condition that if her son should return from the Turks, ‘and the vomit of Mahomet,’ he should be restored to his father’s throne. As a token, her representatives handed over the Sword of the Realm, and the Royal Spurs, ‘which the Pontiff benignantly received, and ordered them to be placed, with the will, in the Apostolic archives.’[125]
