With the Et in Arcadia Ego Sum file open, press the Start Analysis button, and SIDNEY will suggest running an anagram parser on the phrase. Use the menu at the top of the screen and select the anagram parser. While on the anagram screen, scroll down the Latin words on the left side and build the phrase "Arcam dei tango," which means "I touch the tomb of God." SIDNEY will automatically perform a search on the final four letters of the anagram and complete the phrase with "Iesu," which completes the translation of "I touch the tomb of God, Jesus."

Here's what the map looks like after solving the Sagittarius riddle.

While still in SIDNEY, select the ANALYZE function from the top menu and open up the map file. Select the Enter Points function from the top menu. You're placing the red serpent on the map. It's the same shape as the one on the front of the Le Serpent Rouge papers. Locate it just above the Holy of Holies; you'll see what looks like a train track with a tail end near Chateau de Serres. Place one point on the tail end of the track, or serpent, one in the middle, and one in the circle at the other end, the serpent's head. When finished, press the Start Analysis button. With everything completed, and the serpent on the map, the time block concludes.
