When the morning star (either the planet Mars, Jupiter, or some times Venus) rose ringed with red, the priest knew it was the signal for the sacrifice. He directed the men to carry out the rest of the ritual, including the construction of a scaffold outside the village. It was made of sacred woods and leathers from different animals, each of which had important symbolism. It was erected over a pit with elements corresponding to the four cardinal directions. All the elements of the ritual related to symbolic meaning and belief, and were necessary for the renewal of life. The preparations took four days.
