The cock was designed by nature to announce the dawn; by singing they awaken men. They are skilled astronomers, sing at the start of every three hour period, go to bed with the sun, and at the fourth hour of the night awaken us with their song. They duel with each other to determine who will rule, with the winner strutting proudly and the loser forced to serve; a conquered cock does not crow. Some cocks are bred only to fight. Cocks carry themselves so proudly that even the noble lion is afraid of them. Omens and auspices can be read in the behavior of cocks.
