I fixed the "Leonardo Da Vinci" mistake that you pointed out. I guess that I got it mixed up with "Stone Marker".

Here are some more comparisons while I am at it:
The Imperial Purple Robe of Empress Theodora
The Good-Luck Watch of Empress Eugenie- Both episodes dealt with an "Empress".
- Both artifacts dealt with an expensive piece of clothing related to each Empress.
- Both episodes were Green Monkey temple appearances.
- Both Green Monkey teams won two pendants in the temple games.
- Both Green Monkey male contestants had a "J" at the beginning of their names.
- Both frontrunner females were taken out in the Shrine.
- Both of the temple runs ended while the second runner was in the room of the artifact.
The Mysterious Manuscript of Mary ShelleyThe Dried Apple Half of William Tell- Both episodes were produced on the same production day.
- Both episodes use the EXACT same temple games in sequence.
- Both episodes feature the Silver Snakes losing in the temple games.
- Both episodes feature the final temple score being 2-0.5, with the tied game coming from the first individual temple game in each episode.
- Both temple teams had a contestant whose name started with an "L".
- Both teams only entered six rooms of the temple, with the secondrunner in each not making any progress.
