I want to know the answer to the following question:
What event does Raymond E. Brown believe the Toledot Yeshu describes?
All the background I'm provided with is that "The name Panthera may be a distortion of the term parthenos (virgin) and Raymond E. Brown considers the story of Panthera a fanciful explanation of the birth of Jesus which includes very little historical evidence.". Is that enough to answer the question?
Answer: yes
