History of Friedrich II of Prussia, Volume 03 by Thomas Carlyle

In the summer of 1608 (23d May, 1608) Johann Sigismund's (and his Father's) Mother-in-law, the poor Wife of the poor imbecile Duke of Preussen, died. [Maria Eleonora, Duke Wilhelm of Cleve's eldest Daughter: 1550, 1573, 1608 (Hubner, t. 286).] Upon which Johann Sigismund, Heir-Apparent of Brandenburg and its expectancies, was instantly despatched from Berlin, to gather up the threads cut loose by that event, and see that the matter took no damage. On the road thither news reached him that his own Father, old Joachim Friedrich, was dead (18th July, 1608); that he himself was now Kurfurst; [1572, 1608-1619.] and that numerous threads were loose at both ends of his affairs.

The "young man" -- not now so young, being full thirty-five and of fair experience -- was in difficulty, under these overwhelming tidings; and puzzled, for a little, whether to advance or to return. He decided to advance, and settle Prussian matters, where the peril and the risk were; Brandenburg business he could do by rescripts.
