I might have fucked that one up, all I can remember with certainty was there were enough sources that could be cross referenced to include the baptism of a man named jesus by john the baptist and there being mention of like a visual depiction that could be taken as a reliable second source but this was a first year history of religion paper I struggled a lot with so Id take it all with a big grain of salt
All I really remember for sure was historians can (sorta) agree he was baptised by probably john the baptist
