Think about it...
Your great grandpa who lived centuries ago and who is still known for the great inventions that he made in the past wrote you a letter!
Ibn Sina the sultan of doctors
Katip Chelebi the important historian and geographer
Sinan the great architect
Rumi the famous poet and author
Piri Reis the first navigator who drew a world map and
Yunus Emre the poet who captured everyone's hearts with his
 poems wrote you a very special letter. It is very exciting isn't it?
When you read these letters you will both travel to the times
your grandpas lived in and learn about their wonderful works.
Come on kids! Now it is time to read the letters from our
 "Wise Grandpas"...
