'Vopiscus has inserted the letter in the vita Satumini^ c. 8, and says
that he took it from Phlegon's biography of Hadrian. According to its
superscription, (Had. Aug. Serviano consuli salutem) it is directed to
Servianus when he was consul. Now the fasti (Klein, Fasti cottsulares}
name as consuls : Trebius Sergianus for the year 133 A.n., and'L. Julius
Ursus Servianus Cos. iii. for 134 a.d. The superscription may have been
made later, or the word consuli may have been added. The greatest
difficulty seems to lie in the vfordsji/ium tmum Vertitn ; for the adoption
took place only in 136 A.n. Filius^ however, may be merely another ex-
pression for the favourite of Hadrian, and Verus was most likely already
selected to be his successor. He accompanied the emperor in Egypt.
It is unnecessary for (}rcppo, p. 230, to assume a new journey of Hadrian
to Egypt at the close of his career. From the nemo illic^ Casaubon
concludes that the letter was written after Hadrian's departure from
Egypt ; or that he had at least left Alexandria, as he writes himself.
I take the letter as genuine, even though, as the text shows, some
passages have been interpolated. I object less to Xht/iiium meum than
to the repeated reference to the Christians of Alexandria, which cannot
be Hadrianic.
