Nigerian Igbo People Altar Statue: "Alusi"

This is a Nigerian Ibo People "alusi" figure." Often referred to as "statues of ancestors," these sculptures actually represent a deity called Alusi. They were kept in a shrine dedicated to the ancestors, and used during weekly and annual celebrations.

Most Ibo figures are frontal, symmetrical, and upright, with legs slightly spread, arms held away from the body, and hands stretched forward, palms open. Proportions are true to those of the human body, with the exception of the neck, which is longer. The position of the hands facing the sky identifies this figure as an alusi. These open palms symbolizes the generosity of deities and their willingness to receive sacrifices and offerings. It also means "I have nothing to hide."

The statue is scarified to reflect the status of its owner. Young men acquire an alusi at various ages, but they all own one of them by the time they get married and settle down.
