Tiberius Julius Abdes Pantera is a really long name! It's the name of a Roman soldier who lived a long, long time ago. He was from a place called Sidon, which is now in modern-day Lebanon.
Now, Tiberius was a special soldier, because some people believe that he might have been the father of a man named Jesus. That's right, the same Jesus that you might have heard about in stories!
You see, there are some old stories and documents that talk about a young woman named Mary who had a baby named Jesus, but no one knows for sure who his dad was. Some people think that Tiberius might have been his dad, but no one knows for sure because there isn't any hard proof.
So, to sum it up, Tiberius Julius Abdes Pantera was a Roman soldier who might have been the father of Jesus, but we're not exactly sure if that's true or not. It's just a really old and interesting story that some people believe.
