Uli is the name given to the traditional designs drawn by the Igbo people of Nigeria.
Uli drawings are strongly linear and lack perspective; they do, however, balance positive and negative space. Designs are frequently asymmetrical, and are often painted spontaneously. Uli generally is not sacred, apart from those images painted on the walls of shrines and created in conjunction with some community rituals.
The drawing of uli was once practiced throughout most of Igboland, although by 1970 it had lost much of its popularity, and was being kept alive by a handful of contemporary artists. It was usually practiced by women, who would decorate each other's bodies with dark dyes to prepare for village events, such as marriage, title taking, and funerals; designs would sometimes be produced for the most important market days as well. Designs would last about a week.
