The map
Every psalm in the book, in order. Colour is what kind of psalm it is. Width is how long it is - Psalm 117 is the shortest in the Bible at two verses and takes a single square, and Psalm 119 is the longest chapter in the Bible at 176 verses and fills a whole row.
The ones you have read carry a brass dot. That is kept on this device only - there is no account and nothing is sent anywhere.
