Brandenburg wished to form an alliance with Saxony, which lay immediately to its south, and thereby to worry it loose from the stern embrace of Austria. The alliance was to be sealed by the physical union of Johann Georg IV, the Elector of Saxony, with a suitable Princess from the House of Brandenburg. Eleanor was suitable, was available, and was there. And so she had married Johann Georg in Leipzig in 1692 and thereby become Electress of Saxony—so, equal in dignity to Sophie Charlotte, to Sophie, and to the six other Electors of the Holy Roman Empire. The newlyweds had moved to the Saxon electoral court at Dresden (which lay another sixty or so miles up the river from where Eliza was at this moment). Eliza had received a spate of Caroline-letters, and one Eleanor-letter, from there. But after a few months the Caroline-letters had begun to originate from this Pretzsch and the Eleanor-letters had stopped coming altogether. Even the maps of the father of Bonaventure Rossignol did not list any Pretzsch and so Eliza had had to ask Leibniz where it was. "A few hours’ ride from Wittenberg," he had answered, and then declined to say anything more of it, which ought to have signified something to Eliza.
