It was 1472 when a young Leonardo Da Vinci was walking in the crowded markets of Milan, when suddenly a glimpse captured his attention in the edge of his sight, he turned his head only to appreciate an old fashioned middle eastern merchant with beatiful jelwery, it was not that rare to see many easterns at the time, mostly because of the transportation facilities at the time would allow them to reach far distances only to merchant goods from far away. But for this young and eager of knowledge Leonardo, there was something different about this particular eastener.

As he aproached, almost by instintc, the foreigner noticed his presence and welcomed him to his seller mat with a wide smile with a strong accent. - SALVE!. - followed by asking Leonardo about his particular interest, to which Leonardo replied with another question about the foreigner history.

It didnt passed much time until Leonardo turned to be fascinated by the beatiful cultures and origins of this particular merchant, the eastener was pleased with Leonardo's genuine attitude towards seeking wisdom. Then the old merchant reached in one of his skin bags, it was a book with an cover in arabic, translated as "The book of Knowledge by Ismail Al-Jazari"

-Consider this a gift.- The eastener said.

To which Leonardo, in sight, was just about to take the gift without hesitations, but suddenly he took himself in composture and mentioned that regardless the charming encounter, couldnt allow himself to not give something in return.

And before any other word was able to be pronounced out of Da Vinci's mouth, the Old merchant said: -Your investment has been already made, this is my remuneration to you.
