By 1549 Arthur was in the service of Edward Seymour, 1st Duke of Somerset, then Lord Protector. He matriculated as a fellow commoner at Jesus College, Cambridge in 1552. Henry was elected to Parliament in 1558, probably because of Oxford's influence, and from the later 1550s Arthur worked on a translation of Pompeius Trogus that he planned to dedicate to Oxford. But Oxford died in August 1562, and his son Edward, the 17th earl, became a ward in the house of William Cecil, Lord Burghley, in The Strand. Cecil appears to have employed Golding as his nephew's tutor for several years, for two of his dedications are dated from Cecil House, and in 1567 he dated a dedication from Barwicke, one of the de Vere manors near White Colne, Essex.
