This family was praying for so many good things.
Sacrifice was thought to please the gods. If the gods were pleased, then the people would be rewarded with good crops and happiness. This is where that chicken under the preist's arm comes in. On the bottom right of this picture you see a roundish preparation for the next prayer fire. Lots of colors. These are candles. Each colored candle has a significance in the ceremoney. Red is for love. Blue is for luck. Green is for money matters. Yellow is for people over 50 looking for work. And black is for ridding oneself of evil spirits. Slowly as the priest prayed to God they lit the candles and then the coals. Some say the color representation is: yellow, skin; black, hair/night; blue, rain/water; green, earth; red, blood/heart.
