Pilate and Lentulus

Coming upon these two Syriac manuscripts
One by Publius Lentulus and another by Pilate
I've found 5th century Syriac sources
Written in the Syriac tongue---
When translations were fruitful
It would be around the 5th Century AD.
460 years after Christ.
Catholics say, "It is pseudepigraphal
"For no Lentulus ever was Publius."
Although, scholars said Nazareth never existed;
They've even gone so far as to say Israel
Didn't exist until the seventh century B.C..
Which we know is not true.
Why would translation work be done
And then hidden until the Renascence?
Mystery upon mystery.
