Final answer:
Leonardo da Vinci's version of The Last Supper is remarkable for its depiction of real people acting like real people.
Step-by-step explanation:
Leonardo da Vinci's version of The Last Supper is remarkable for several reasons. Firstly, it is not the first painting of The Last Supper, as there have been other depictions before da Vinci's. Secondly, it is not the only painting of The Last Supper, as there have been other artists who have painted this subject as well. Thirdly, while it is certainly a famous painting, it may not be accurate to claim that it is the most famous painting of The Last Supper, as that is subjective and can vary depending on individual opinions and interpretations. Finally, da Vinci's version of The Last Supper is significant because it is considered one of the first paintings to depict real people acting like real people. The figures in the painting appear in dynamic and natural poses, showing emotions and reactions that give them a lifelike quality.
