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).

Ọba gha ye Ivie gie ọwan, ẹ ghi tama rẹn ehe nọ gha bae yi (When the Ọba gifts you a bead, he doesn’t tell you how to wear it) (Daniel Inneh, pers. comm., 27 September 2025).

Iviawẹ (also spelled ĺvîowẹ) are coral-beaded anklets, often worn stacked together (Aigbe 1985, p. 28; Okpokunu, Agbontaen-Eghafona & Ojo 2005, p. 162; Ọbazee 2025, p. 279). Many of the figures depicted on the Emwin Arhe (royal treasures) in brass, bronze, ivory, and wood are shown wearing these. According to Daniel Inneh (pers. comm., 27 September 2025), beads were sent to people whom the Ọba wished to honour, although there was no directive on how to wear them.

Mostly, people who wear Iviawẹ are identified as palace chiefs or priests and priestesses. However, today anyone can wear them as cultural identifiers or fashion pieces.

The Ubanu'hi (infinity symbol) is a kind of guilloche or interlaced strapwork motif that can be angular or rounded. It was used by Edo artists in the decoration of many Emwin Arhe (royal treasures) and is ubiquitous in Benin royal arts. Ubanu'hi is a shortened form of “uba no Ọba ya de agbon ke ehimwin yi”, which means “the rope with which the Ọba ties the heaven and earth together” (pers. comm. Chief John Igbineweka Inneh n’Igbesawman, 2022). Similarly, Paula Ben-Amos Girshick (in Plankensteiner 2007, pp. 339, 341) described this as “Ọba n’iri agbon”, or the “rope of the world” pattern.

According to Ọbabanmu Ineh (in Blackmun 1984, p. 51), the use of this motif indicates that objects were carved by members of the Igbesanmwan. However, the motif is found on all types of Emwin Arhe (royal treasures), not only those made of ivory or wood. On the flanges of the Ama (relief plaques) alone, Kathryn Gunsch (2018, pp. 75–77) identified three different versions of the Ubanu'hi and, through her analysis of over 850 plaques, found that these different Ubanu'hi forms align with other characteristics, such as dimensions, the prevalence of ornamental motifs, and stylistic qualities. Together, these provide evidence, she argues, of different production groups among the plaque makers .

Kate Ezra (1992, pp. 209, 264) went on to argue that the use of these motifs indicates that certain objects were used in a “royal context” and were associated with “royal patronage”.

Odigba (coral-beaded collar) is a rigid neck collar made of coral beads, worn as part of ceremonial attire only by senior princes who have been made Enigie (Inneh 2007, p. 107). Although Ibafe (2007, p. 43) argued that the Odigba was introduced during the Ogiso period (c. 900–c. 1170 AD) by Ogiso Ere, along with other symbolically important Emwin Arhe, such as the Ada (ceremonial sword) and the Ẹbẹn (ceremonial sword), this seems unlikely, as coral was only introduced in the late 15th century through trade with Portuguese merchants.

Àkpólú, also spelt Àkpólo, are strings of coral beads worn around the lower waist or hips by women and girls ( ; Ọbazee 2025, p. 23). Before colonial rule in the Benin Kingdom, children were traditionally not permitted to wear clothing until the Ọba gave them cloth to wear; the Àkpólú was an exception to this practice, allowing children to wear these coral bead strands around the waist ( ).

Ugianranran (manillas) are highly important objects in the visual language of the Emwin Arhe (royal treasures). Although Ugianranran were made in a variety of sizes, forms, and weights, they share the characteristics of being made from copper or copper alloys, namely brass or bronze, and having a curved, ring- or horseshoe-shaped form.

In the early years of trade between the Portuguese and Edo, during the late 15th and early 16th centuries, manillas were made primarily of copper. During the early 16th century, Edo traders increasingly sought manillas made of brass. This changing preference is believed to have corresponded with the growing demand for brass among artists of the Igun-Ẹrọnmwọn ( ). During the 17th and early 18th centuries, the Dutch also traded manillas with the Edo, although to a lesser extent than the Portuguese. Recent scientific analysis has shown similarities between the composition of metals in manillas from the southern Rhineland region of Germany and the copper alloys used in some Emwin Arhe, supporting earlier scholarship suggesting that manillas were used by casters to produce Emwin Arhe (Skowronek et al. 2023).

When depicted on objects, Ugianranran are often shown alongside or being held by figures identified as Portuguese. In one case, figures identified as Benin traders or royal emissaries are shown holding manillas in their hands ( ). This is particularly the case on the Ama-Ẹrọnmwọn (bronze relief plaques), which are believed to have been commissioned by Ọba Esigie. Esigie is understood to have encouraged the production of artworks, made possible in part by the increased supply of manillas and other copper-alloy objects resulting from trade ( ). Ugianranran are therefore associated with overseas trade, wealth, and Olokun, the deity of the seas ( ). In addition to being held by figures or appearing alongside them on artworks, Ugianranran sometimes serve as focal decorative motifs, further indicating their symbolic and economic potency.
