It was only natural that Ferdinand, the brother of Charles V., should send an ambassador to represent him at the marriage of his nephew to the daughter of his unfortunate aunt, Catherine of Aragon. For this purpose he selected a Spanish gentleman, Don Pedro Lasso de Castilla,[66] who had been the companion of his boyhood in Spain, and had since continued to be a member of his household. With him Busbecq went as attaché. In the life appended to the Elzevir edition of Busbecq’s letters, we are told that he joined the embassy on Don Pedro’s invitation; but in a document of infinitely higher authority, the Patent of knighthood given in the Appendix, it is distinctly stated that the summons came from Ferdinand himself, who thus adopted into his service the grandson of the écuyer trenchant who had served his brother, his father, and his great-grandfather.

In order to mark the importance of the occasion, Don Pedro Lasso was attended to England by a numerous train, many of whom were gentlemen. Altogether there were nearly seventy persons in his suite.[67]

The arrival of this embassy was peculiarly gratifying to Queen Mary, and she caused Don Pedro and his staff to be received with special honours. As they entered London, June 26, 1554, a salute was fired from the Tower, a compliment which excited the jealousy of Noailles, the French ambassador.[68]

Busbecq must have had no ordinary powers as a linguist, for we have it on the authority of his contemporary, L. Guicciardini, that there were six languages with which he was as familiar and ready as with his mother tongue (Flemish). These were Latin, Italian, French, Spanish, German, and Slav; unfortunately, a knowledge of English was not amongst the number of his accomplishments, and this may partially account for the absence in his letters of any allusion to the manners and customs of our country. It is much to be regretted that we have not got some record of his visit; if he acted as secretary, as is supposed, possibly his despatches from England may still be lying among the archives at Vienna to gladden the heart of some future discoverer.

Don Pedro Lasso with Busbecq and the rest of his suite, stayed in England till October 1554. They then took leave of the Queen, and travelled down to Dover with the intention of crossing over to the Continent. Here they found themselves stopped. Every day French vessels could be seen hovering off the harbour in search of a Prize. The Ambassador found it necessary to write[69] to Queen Mary, reminding her that he had only come to England by his master’s orders to do honour to her nuptials, and asking her to give such instructions as would ensure his safe departure. It is not likely that an ambassador who was received with such high distinction made so reasonable a request in vain, and there can therefore be little doubt, that Busbecq and his chief were escorted to Calais by a squadron of English ships manned with stout sailors from the Cinque Ports.

On reaching the Netherlands, the embassy was broken up, Don Pedro repaired to Brussels, and Busbecq went back to his friends and relatives. It is evident that the young diplomatist had impressed his chief with a very high idea of his ability and discretion, for a few days after his return from England, whilst staying with his aunt Marie Ghiselin, at Lille, he received a summons from Ferdinand to undertake the duties of ambassador at Constantinople. He was called to a most difficult and apparently hopeless task.

Ferdinand of Austria, King of the Romans, and afterwards Emperor, Sovereign of Hungary and Bohemia, was in a most critical position; it is no exaggeration to say that he and his kingdoms lay at the mercy of the Sultan, who might any day annihilate his forces, and take possession of his dominions. His only hope of rescuing his subjects from slavery lay in the skill of his ambassadors. In 1545 Gerard Veltwick[70] (Velduvic), had been sent to represent the two brothers, Charles V. and Ferdinand, at the Turkish court; on his return, John Maria Malvezzi, one of his companions, had succeeded to the post. Malvezzi was not fortunate; the Turks regarded an ambassador simply in the light of a hostage,[71] and when Ferdinand in the autumn of 1551 broke faith with them by taking possession of Transylvania, they threw Malvezzi into a horrible dungeon; there the unfortunate man remained till August 1553, when his release was procured by Francis Zay and Antony Wranczy (Verantius) afterwards Bishop of Erlau, who came to Constantinople as Ferdinand’s representatives.

Malvezzi returned to Vienna broken in health by his sufferings in the Turkish dungeon. It was not long, however, before Ferdinand ordered him to resume his duties at Constantinople; Malvezzi did his utmost to comply with his master’s wish; he struggled as far as Komorn and there broke down. Ferdinand suspected him of pretending to be worse than he really was, in order to avoid a post of the perils of which he had had such painful experience. As Busbecq forcibly remarks, Malvezzi’s death a few months later removed this doubt!

Ferdinand had need of some one to succeed Malvezzi. It was not an enviable post, and the courtiers of Vienna had no fancy for the risk of being slowly done to death in some noisome dungeon at Constantinople, or of returning, as the Pashas at one time intended Busbecq should return, noseless and earless! But Ferdinand felt that it was absolutely necessary to have a representative at the Turkish Court to assist him in staving off the evil day. Accordingly he sent a summons to Busbecq, and at the same time despatched a message to his late chief, Don Pedro Lasso, asking him to use his influence with the young diplomatist, and urge him to start at once for Vienna. It would seem as if the post were but little coveted, when such pressure had to be applied. Busbecq, however, needed no urging; he was a man capable of finding intense pleasure in new scenes, new work, new discoveries, and all were included in the prospect now opening to his eager eyes.

It was on November 3, 1554, that Ogier received Ferdinand’s message. He at once started for Bousbecque, and paid a last visit of love to his father, his friends, and the home that was so dear to him. Thence he hurried off to Brussels, where he had an interview with his old chief, and before many hours were past he was galloping along the road to Vienna. A comparison of dates will show how very prompt Busbecq must have been. He received the summons on November 3, and by the eighteenth he had reached Vienna, having paid at least two visits in the meantime, and made his preparations for his distant journey. It was probably at Bousbecque that he enlisted the followers who were to accompany him in his long and perilous expedition; it is evident that they were Flemings, sturdy fellows who knew no fear, fond of a bottle of wine, and not averse to a practical joke.[72] There were amongst them men of fair education,[73] who had perhaps been trained in the chapter-school of Comines, and there was one man of eminent ability, who came from the neighbouring town of Courtrai, William Quacquelben.[74] He acted as physician to the party, and at first seems to have occupied a position little differing from that of a servant; how Busbecq learnt to love and appreciate him will be told in his own words.
