there is such variety among igbo groups that it is not possible to define a general igbo art style. igbo art is known for various types of masquerade, masks and outfits symbolising people, animals, or abstract conceptions. bronze castings found in the town of igbo ukwu from the 9th century, constitute the earliest sculptures discovered in igboland. here, the grave of a well-established man of distinction and a ritual store, dating from the 9th century ad, contained both chased copper objects and elaborate castings of leaded bronze. along with these bronzes were 165,000 glass beads said to have originated in egypt, venice and india. some popular igbo art styles include uli designs. the majority of the igbo carve and use masks, although the function of masks vary from community to community.
