Louvre museum question.?

I%26#039;ve been to france last summer and i%26#039;ve seen a painting not far enough from the mona lisa, it was in the hallway, there was a painting that made me think about the story behind, the painting was a portrait of a young man in his 20%26#039;s and he had sdoulder length hair and the painting next to it had a portrait of his brother i think then they had a portrait of the two together, who are these 2 men?
Louvre museum question.?
It could have been a painting of Jesus and John the Baptist, also by Leonardo da Vinci (and, in my opinion, more interesting than the Mona Lisa!).


Have you tried taking a %26quot;virtual tour%26quot; through the Louvre? I don%26#039;t know if this is possible or if they only %26quot;highlight%26quot; the most familiar works...but it%26#039;s worth a try!
