Thank you. It is an interesting list, a model of selection bias turned comical. I think it near inconceivable that you are actually familiar with their works, and I would encourage anyone interested to submit each name to Wikipedia come to their own conclusions.
All?
Pliny the Younger (61 CE -- c. 113 CE)
Dio Chrysostom (c, 40 CE -- c. 115 CE)
Quintus Curtius Rufus (unknown)
I guess, to be fair, we should give you the latter. On the other hand, according to Wikipedia:
Alexander the Great reigned 335 -- 323 BCE and the Quintus Curtius Rufus Historiae is unlikely to have a great deal to say about Jesus. That you would cherry-pick this historian and dismiss Josephus pretty much tells us everything we need to know.
BTW, the historicity of Jesus has been discussed ad nauseam here at RF. The search function is your friend.
