she did not know, on the faith of portrait painters.” She then hinted that she wished Charles to visit her in person, even if he came in disguise. Her thirst for admiration and homage was insatiable, and, popular parvenue as she was, the idea of princes of spotless lineage humbling themselves before her very nearly led her into a quagmire more than once. She probably had not the slightest intention of marrying Charles at the time, but it would he been a great feather in her cap if she could he brought a prince of the house of Austria as a suitor to her feet.

rts and great merits, and if she had to marry a subject she had a great liking for him.” Referring to Mary of Scotland’s recent marriage with Darnley, she said that if she married Leicester two neiouring queens would be wedded in the same way. “She is so nimble in her dealing and threads in and out of this business in such a way that her most intimate fourites fail to understand her, and her intentions are, therefore, variously interpreted.” In the meanwhile both the Archduke’s and Leicester’s friends were confident that their respective suits were prospering, although Leicester either was, or feigned to be, bitterly jealous of the Queen’s new flame, his erstwhile bosom friend Heneage, with whom he had another noi
