At that time, there was a buffalo, Thoraphi, leader of a great herd of cows and possessed of unparalleled strength.  In order to get rid of a male competitor, whenever a bull-calf was born, he would kill him at once.   When one cow showed signs of bearing another calf, she went into a cave, so that she might protect her young one from being crushed to death by its own father.  The calf was duly born and took also the name Thoraphi.  When he came to his youth, he went out and killed his father.
