Book of Erœ

In a tradition said to originate from the first of the Tyàtyo scholars, every Tyàyi family maintains a book filled with sheaf of red parchment. The outer edges of each parchment, appear more red than the others as they are stained with the blood of every generation of the family. Every child of the family learns to write his first word "Itsœ" on those sheets of paper, which are then preserved for posterity, as knowledge learnt should not be forgotten, especially the words of the Bets.
