An interesting history preserved in Westcar Papyrus (document written at the beginning of dynasty XVIII, about 1550 b.C).
The King Sefeneru felt so bored and depressed, and vainly he looked for in every salon of the palace anything to make him happy. At the end he ordered to call Tchatcha-en-Anque, the main priest and scribe of the registers, to whom he told his entire affliction.
Tchatcha-en-Anque thought the king should order to make a ship, in which the royal priestess should go with him for sightseeing, oaring in the lake. By this way the king ordered 20 golden oars that should be used by 20 ladies. All those priestess well dressed and wearing semi-precious rocks.
The king’s heart was so happy with this sightsee, but one of those priestess lost her jewel in water and she stopped singing. So all her partners did the same and stopped.
Sefeneru wanted to know the reason and reason and they answered: “Our coxswain doesn’t oar.”
So the king asked to the priestess why didn’t she oar. “Oh!” she groaned and answered him. – “my turquoise felt into water and my heart is so sad.” The king asked her to keep happy; because he would give her another one, but she answered she wanted her turquoise back. So the king called for Tchatcha-en-Anque and told him what happened.
So, the priest screamed some words and suddenly the lake waters were divided by two and all of them could see the jewel. Tchatcha-en-Anque went down from the ship, took the jewel and gave it back to the owner. After that he screamed another magical words and the lake came back, softly and clean.
This happened made all hearts happy and Tchatcha-en-Anque was rewarded for his ability. Kufu, Pharao from IV Dynasty enjoyed so much this legend he ordered a gift o Seneferu’s Ka.
Curiosity
Do you know turquoise is known as belly dancers’ rock? And it’s also a lucky rock in Arabian culture.
To Think
Water division was already known before Moyses in the Holy Bible, dates the papyrus. Legend or not it’s written.
