The legend goes through a few hundred years.

There was a village at the edge of Pará river, in the Amazon Forest, Brazil, that population grew very rapidly. Due to this increase in population, food became scarce. Itaki, the tribal leader, worry and concerned to feed his village, decreed that people could not have any more children and after that moment, any newborn child should be sacrificed.

One day Itaki's daughter got pregnant.
During pregnancy, she prayed to her God, that he would show her father a food that could save the tribe. But nothing happened.

The child was born, and the lovely girl was sacrificed. The mother was devastated and completely destroyed. She cried days and nights, ate no food and locked herself in the hut for days.

One night, she heard her daughter crying in the forest. She ran in the direction of that sound, and there she saw her daughter on the side of a slender palm tree. When she tried to hug her baby, the image disappeared. The next day the tribe found her dead with a smile on her face, embracing the palm tree and with open eyes, looking up, to the many bunches of dark purple fruits.

The tribe harvested fruits of which they obtained a reddish wine, that soon became the diet for the tribe.

Itaki called the fruit Açaí in memory of his daughter. He lifted the ban and the tribe began to prosper again. Today that population is known as Belém, in Pará State, Brazil.
