Depictions of Ewi (mudfish) are among the most frequent motifs in the Emwin Arhe (royal treasures). Mudfish hold an important place in Edo belief, both as representations of the god Olokun and as symbols of royalty (Plankensteiner 2007, p. 410), as well as of “prosperity, peace, well-being and fertility” (Ben-Amos 1976, p. 245). Mudfish are also particularly common animals for sacrifice, and mudfish-shaped Orhiẹvbẹ (kola-nut boxes) were used to make offerings or store kola nuts.

Yet, the appearance of Ewi across the Emwin Arhe is not consistent, and it has been argued that different species of mudfish were depicted by Edo artists, each with different qualities and capabilities. For example, the electric shock of Malapterurus electricus resembles the fierceness of the Ọba, while the liminal qualities of the Synodontis clarias mudfish, which lives both on land and in water, similarly reflect the Ọba’s rule over land and sea (Gallagher 1983, p. 93). With these different qualities in mind, the mudfish is an important symbol of Benin kingship and royalty.

Sometimes the Ọba was depicted by artists with mudfish rather than legs (see Ọba with Mudfish Legs).

The Udahae is a forehead band made from coral beads and worn by chiefs. Sometimes a white Igan (feather) from the Oɛɣohɔ (vulturine fish eagle) is tucked into the left side of the Udahae. According to Benin oral tradition, the Udahae was introduced by Ọba Ezoti, the first son of Ọba Ewuare I. During his coronation, Ezoti was shot in the forehead with a poisoned arrow. To stop the bleeding, a band of red beads was wrapped around his forehead while he made public appearances. Fourteen days later, he died from his wound. Since then, Benin chiefs have worn the red-beaded Udahae around their foreheads to commemorate the cap used by Ezoti to stop the bleeding (Egharevba 1968, p. 21).

The Ititi ako is a cluster of coral beads, usually three or four, attached to a pin and used to embellish the royal crowns on Uhunmwu-Elao (commemorative heads) and Uhunmwu-Ẹkuẹ (pendant masks). These bead clusters are also known as star beads, which indicate the prosperous destiny of an individual or wearer. Apart from enhancing the appearance of the wearer, they also represent the individual’s high social status. Judging from their presence on a variety of head sculptures, both men and women wore Ititi ako.
