Travels
During the 1570s Robert Corbet travelled widely in mainland Europe, sometimes in company with Philip Sidney, an alumnus of Shrewsbury School whose father, Sir Henry Sidney, was president of the Council in the Marches and a close friend of Sir Andrew Corbet, who was formally recognised as his deputy in 1574.
On 15 April 1574 Sidney, residing in Venice, recommended Corbet in a letter to Hubert Languet, a Huguenot who acted as diplomatic representative of Augustus, Elector of Saxony and who was at that time at the court of Maximilian II, the Holy Roman Emperor in Vienna:
"In a few days you will see two noble Englishmen, to whom I shall give letters of introduction to you, and therefore it seems well to write a few words to precede their arrival, and prepare you to receive them with your wonted courtesy. The one whom I especially commend to you is Master Robert Corbet, my very greatest friend, a man of high birth, but one who, as Buchanan says, ‘in excellence of parts outdoes his birth’. He is of the right side in religion and not unpractised in the art of war; he speaks only Italian The other is Master Richard Shelley, my cousin, as also is Corbett, but nearer to me in blood as the other in friendship."
Shelley, Corbet's travelling companion on this occasion was last grand prior of the Knights of St. John in England, a Catholic notable who resided in Venice acting informally as the queen's trade representative and even less formally as a spy for the English government. Corbet set out for Vienna on 27 May, without his servant, who was too ill for the journey, but carrying a portrait of Sidney for Languet. After a brief stay in Vienna, Corbet and Shelly set out with letters of introduction from Languet to friends in Prague, Nuremberg and Augsburg. However, Corbet was soon writing back from Prague to Languet that Shelley was too ill to proceed, which Languet initially put down to Shelley's hypochondria. However, wrote Languet:
"alas he made a more just calculation of his danger than the physicians, as I learn from a second letter from our friend Corbet, who writes in despair of Richard's condition. He was at the point of death, given over by his physicians...Corbet's letter shows that he is greatly disturbed, and I do not wonder at it. He consults me about his own affairs, and asks whether he shall pursue his journey when he has lost his companion as he hears that troops are being raised in the places through which his road lies, and that all the country about the Rhine and Lorraine is in a state of great confusion. But as he intimates that he will not leave Prague until he receives my reply, I have written to him to say what I think he should do."
The regions mentioned as being in turmoil suggest that Corbet and Shelley were now making for England. Shelley survived his illness and Corbet arrived home the following year, receiving a present valued at £1 13s. 4d. from the borough of Shrewsbury on his return.
The journeys that can be reconstructed from the Sidney-Languet correspondence may be typical rather than exhaustive. A tribute in Shrewsbury's manuscript chronicle after his death says that Corbet was
"of great estimation with the Queen’s Majesty and the nobility because he could speak perfectly sundry foreign languages by reason of his long absence in his youth out of England in foreign countries and especially trained as it were in the Emperor’s court, who was like to have come to great worship had he lived."
