Congratulations! You solved the puzzle and now you’re ready to learn about what you’ll need to solve the puzzles in “A President For His Country”.
The puzzle we’ll be seeing there is called, as you solved, the “Jefferson Disk”. It was a puzzle system created by US President Thomas Jefferson to send coded messages during the American Revolution. Examples of his wheel cipher can be seen at Monticello, a former estate of Thomas Jefferson’s in Virginia that is now a museum.
But of course, this is a story about a Latvian president as well, so the codes used here will not use Jefferson’s model, but one adapted for the Latvian alphabet.
Read about Jefferson’s cipher on the Monticello website and on Wikipedia.
Read about the Latvian alphabet here on Wikipedia. Also remember the time periods!
