Task: Question Generation
Input (English): Passage: In 1654, after a decade in Rome, Wright travelled to Brussels where his abilities were recognised by Archduke Leopold Wilhelm of Austria then governor of the Spanish Netherlands. Leopold employed him not as an artist, but as an advisor on antiquities. As the younger brother of the Emperor Ferdinand III and cousin of Philip IV of Spain, the Archduke had the wherewithal to amass a large collection of paintings and antiquities. Moreover, in the spring of 1655, the Archduke was enjoying a period of cordial relations with Oliver Cromwell, then Lord Protector of England. (Indeed, the two had been exchanging gifts of horses, and Leopold had provided Cromwell with choice tapestries and other artefacts for the refurbishment of the Palace of Whitehall. Cromwell also received an embassy from the Habsburgs congratulating him on his new office.) 
Since the execution of Charles I in 1649, Leopold had been purchasing artworks from the royal collections and those of various aristocrats, and, against this background, commissioned Wright to travel to London and acquire further specimens. A passport was issued to him as "'Juan Miguel Rita, pintor Ingles, qua va a Inglaterra a procurar pinturas, medalas, antiguedades, y otras costa señaladas, que le hemosencargado..." to allow him to travel to England. The passport is dated 22 May 1655, and signed by the Archduke at Brussels, indicating that Wright had left Italy for Flanders by this time. (The addition of the saint's name name, John, probably marks his conversion to Roman Catholicism at some time prior.)
As one on an official mission, Wright would probably have offered greetings to Leopold's ambassador extraordinary in London, the Marqués de Lede, and to Alonso de Cárdenas, the regular Habsburg ambassador, who had also been engaged since 1649 in art procurement for the Spanish Monarch. The lack of records means that the timing and duration of this visit remain uncertain. However, de Lede left in late June, and de Cárdenas a few weeks later – as relations between Cromwell and the Habsburgs deteriorated – so Wright probably arrived back in Flanders, with any acquisitions he had made, just in time to learn of the Archduke's impending departure – and that of his huge art collection – from Brussels in the autumn of 1655.
Output (English): What is the first name of the Archduke about whose impending departure to Brussels Wright learned on the return to Flanders?
