The Emperor Hadrian spent much time during his reign touring his Empire, and arrived in Claudiopolis in June 123, which was probably when he first encountered Antinous. Given Hadrian's personality, Lambert thought it unlikely that they had become lovers at this point, instead suggesting it probable that Antinous had been selected to be sent to Italy, where he was probably schooled at the imperial paedagogium at the Caelian Hill. Hadrian meanwhile had continued to tour the Empire, only returning to Italy in September 125, when he settled into his villa at Tibur. It was at some point over the following three years that Antinous became his personal favourite, for by the time he left for Greece three years later, he brought Antinous with him in his personal retinue.
