This pair of memorial figures, as well as their beaded cloaks, were created by the same artist. The tripartite composition of the garments may be a symbolic reference to twins followed by the next child who would be called Idowu, Esu l’ehin ibeji (Idowu, the Esu that follows twins). The central form in one of the beaded garments is a head, with two eyes represented by white beads. The second garment is similar, but more abstract.
