Oxford had the honour of his education, under the tuition of Dr. Thomas Thornton, canon of Christ Church.  At the university he remained till he was 17 years of age, and in June 1572 set out on his travels.  On the 24th of August following, when the massacre fell out at Paris, he was then there, [1] and with other Englishmen took shelter in Sir Francis Walsingham’s house, her Majesty’s ambassador at that court.  When this storm subsided, he departed from Paris, went through Lorrain, and by Strasburgh and Heydelburgh, to Francfort, in September or October following; where he settled for some time, and was entertained, agent for the duke of Saxony.  At his return, her Majesty was one of the first who distinguished his great abilities, and, as proud of so rich a treasure, she sent him ambassador to Rodolph the emperor, to condole him on the death of Maximilian, and also to other princes of Germany.  The next year, 1577, he went to the court of that gallant prince Don John de Austria, Viceroy in the low countries for the king of Spain.  Don John was the proudest man in his time; haughty and imperious in his behaviour, and always used the foreign ambassadors, who came to his court, with unsufferable insolence and superiority:  At first he paid but little respect to Sidney on account of his youth, and seeming inexperience; but having had occasion to hear him talk, and give some account of the manners of every court where he had been, he was so struck with his vivacity, the propriety of his observations, and the lustre of his parts, that he ever afterwards used him with familiarity, and paid him more respect in his private character, than he did to any ambassador from whatever court.  Some years after this, Wood observes, that in a book called Cabala, he set forth his reasons why the marriage of the queen with the duke of Anjou was disadvantageous to the nation.  This address was written at the desire of the earl of Leicester, his uncle; upon which, a quarrel happened between him and the earl of Oxford, which perhaps occasioned his retirement from court for two years, when he wrote that renowned romance called Arcadia.  We find him again in high favour, when the treaty of marriage was renewed; he was engaged with Sir Fulk Greville in tilting, for the diversion of the court; and at the departure of the duke of Anjou from England, he attended him to Antwerp [2].

On the 8th of January, 1582, he received the honour of knighthood from the queen; and in the beginning of the year 1585, he designed an expedition with Sir Francis Drake into America; but being hindered by the Queen, who thought the court would be deficient without him, he was made Governor of Flushing, (about that time delivered to the Queen for one of the cautionary-towns) and General of the Horse.  In both these places of important trust, his behaviour in point of prudence and valour was irreproachable, and gained additional honour to his country, especially when in July 1586 he surprized Axil, and preserved the lives and reputation
