Livy? Really?
en.wikipedia.org
Titus Livius (Latin:
[ˈtitus ˈliːwius]; 59 BC – AD 17), known in English as
Livy (
/ˈlɪvi/ LIV-ee), was a
Roman historian. He wrote a monumental history of
Rome and the Roman people, titled
Ab Urbe Condita, ''From the Founding of the City'', covering the period from the earliest legends of Rome before the traditional founding in 753 BC through the reign of
Augustus in Livy's own lifetime.
Now, please note, Livy died in 17 AD. He wrote his histories of Rome (none of which mention Jesus) well before that, when Augustus was Emperor. Most purveyors of the Jesus Myth hold that Jesus was crucified between 29 AD and 33 AD. (Again, they can't give you an exact date, which should raise all sorts of red flags.) during the time Pontius Pilate was Prefect of Judea (26 AD to 36AD)
So how could Livy write about stuff that happened after he died.
You are probably thinking of either Suetonius or Tacitus, who wrote histories later.
Suetonius recorded that Claudius expelled the Jews from Rome because one "Chrestus" was stirring up trouble. Suetonius didn't write his history until the Second Century. Tacititus gives a very detailed version of how Nero prosecuted Christian after the Great Fire of Rome in 66 AD, but his is dubious at best, and seems like the invention of later scribes inserting it in transcription.
