Igan (feathers) are commonly depicted tucked into the headdresses and hats of chiefs represented on Emwin Arre (royal treasures). These feathers are from the Oɛɣohɔ (vulturine fish eagle) and symbolise respected old age and proper chieftaincy ( ).

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).

Ikele is a single stiff string or circlet of coral beads. It is worn by chiefs, such as senior chiefs who have been made Enigie (Inneh 2007, p.107), and is a sign of nobility and rank. The Ikele may only be worn once the Ọba has conferred a person with the right to wear the beads, and the Ikele must always be worn when appearing before the Ọba. According to Ekhaguosa Aisien (in Plankensteiner 2007, cat. nr. 301, p.512) when a chief is wearing the Ikele, they may not eat nor drink in public, and they “constitute an embassy of the Benin Palace wherever he might be.”

Iwu are facial and body markings (scarifications) that were historically worn by Edo men and women. However, since the 1960s, the practice has been nearly extinct (Aisien 2011). In the past, Iwu were used as a way of proving that one was an Edo citizen, and the ceremony of having Iwu completed was an important rite of passage for men and women. The Osiwu, who also practised circumcision and other surgical procedures, would carry out the procedure of adding Iwu. There are different types of Iwu: ‘blades’ worn on the torso (Iwu-eko), and those worn on the face, such as Ikharo (three or four markings above the eyebrows), Irho (two narrow ‘blades’ worn on each cheek), Ovbihue (nasal ‘blades’), Ovbi-agbanmwen (chin ‘blade’), and Igho-okpa/Ukpgho (three forehead ‘blades’) (Aisien 2011, p. 22).

The number of Iwu also varied depending on the identity of the person wearing them. For example, royal men would wear six ‘blades’ on their torso, whilst men who were not royal would wear seven ‘blades’. Meanwhile, the Ọba’s female children would wear fifteen ‘blades’, and all other women would wear sixteen (Aisien 2011).

The Ada is a symbol of authority usually borne in the presence of the Ọba by a designated holder, the Omada, which translates as ‘Ada bearer’. The Ọba has almost exclusive rights to the use of the Ada, except when he permits titled chiefs, such as the Oliha, to possess one. During the Ogiso period, predating the current Ọba dynasty, the Ada is said to have been a symbol of ancestral power, with the ability to control the future (Ben-Amos 1995, p. 25). The Ada is ranked higher than the Ẹbẹn, another symbolically important ceremonial sword.

The Ukpan obọ eva (coral-bead crossed baldrics) were worn as part of the ehaingbehia, the full ceremonial regalia, by only high-ranking members of the palace, including the Ọba himself, the Iy’Ọba, the Edaiken, and the Ezọmọ (Ben-Amos 1999, pp. 68, 141; Osadolor in Plankensteiner 2007, cat. no. 70, pp. 322–323).

Ẹbẹn are a type of ceremonial sword of significant importance in the Benin Kingdom. During ceremonies, titled chiefs would hold them or toss them during dances, thereby paying homage to the Ọba at these public events, particularly when a chief receives a certain status. It is forbidden for Ẹbẹn to touch the ground, so the chief must take extra precautions to avoid dropping the Ẹbẹn during the dance. Therefore, the Okae-Odionmwan (head of executioners) dances with the Umozo (warfare or executioner’s sword) behind the dancing chief.

There are two central ceremonial swords used in the royal court of the Benin Kingdom, one of which is the Ẹbẹn, along with the Ada (ceremonial swords). They are distinguished by their blades: the Ẹbẹn blade reflects the shape of a leaf or an oar. Sometimes, it is decorated with openwork designs and/or brass inlays, most commonly shaped as small Ẹbẹn and Ẹkpẹn (leopards). The handle of the Ẹbẹn also has an unusual ring-shaped form, which further differentiates it from the Ada.
