Suddenly they saw a hill with an old oak and an eagle on top. Lech said: this white eagle I will adopt as an emblem of my people, and around this oak I will build my stronghold, and because of the eagle nest. I will call it Gniezno. The other brothers went further on to find a place for their people. Czech went to the South and Rus went to the East.
