== There is no evidence Hadrian stated in his autobiography that he was born in Rome. == 

 :This is a conjecture of the Wikipedia article, based on a faulty reading of the 'Augustan History' biography of Hadrian, purportedly written by one Aelius Spartianus. 
 :I refer to the actual text of the biography.

 :In the opening paragraph of the the biography, only one reference is made to claims Hadrian made himself in his autobiography: 
 :"The original home of the family of the Emperor Hadrian was Picenum, the later, Spain; for Hadrian himself relates in his autobiography1 that his forefathers came from Hadria, but settled at Italica in the time of the Scipios." 
 :However, the mention of Hadrian's birth in Rome is an inference of the Augustan History biographer: 
 :"Hadrian was born in Rome on the ninth day before the Kalends of February in the seventh consulship of Vespasian and the fifth of Titus." 
 :Nevertheless, the footnote referring this claim in the English translation (Loeb Classical Library) says: 
 :"This is, of course, a fiction, and the biography contradicts itself, for Italica is clearly the patria referred to in c. ii.1 and 2, and c. xix.1." 
 :As for the reference to Hadrian's own autobiography, the footnote says: 
 :"For the Autobiography of Hadrian, now lost, cf. c. xvi. It seems to have been written toward the close of his life, and, to judge from scanty citations from it, its purpose was to contradict current statements about himself which he considered derogatory to his reputation and to present him in a favourable light to posterity."
