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.

Osisi is the general Edo word for guns. Osisi were initially introduced to the Benin Kingdom by the Portuguese from the late 16th century onwards and were again traded by the Dutch from the early 17th century (Osadolor 2007, p. 80). Osisi are usually represented as being carried by, or positioned close to, figures identified as Portuguese based on their attire and hairstyles. There are a small number of exceptions, including two wooden carved examples. One is a possible chair seat where a figure is holding a gun upright, and another is a carved wooden panel where a gun is shown next to an Edo dignitary. Additionally, a more recent work produced by the artist H. I. Erhabor includes an Edo figure holding a gun.

These weapons quickly became a potent symbol in the work of artists from the royal guilds, representing the Ọba’s military might, expansionist policies, and the wealth derived from foreign trade (Plankensteiner 2007, p. 208). Three different kinds of European-manufactured guns were used by the Edo army: the flintlock, the wheellock, and later the matchlock, which was used from the 1600s until around 1850. However, Ọba Akengbuda became increasingly wary of Edo dependence on European firearms and encouraged the production of firearms by the Igun Ematon. During the 19th century, the trade in firearms from Europe resumed, with Dane guns, so named because they were made in Denmark. However, from 1890, European imperial powers banned the trade in firearms to West Africa (Osadolor 2007, pp. 80–81).

The Ewu ivie (coral bead shirt) is made of strings of coral beads. This heavy shirt was part of the ceremonial regalia worn only by a small number of high-ranking members of the palace: the Ọba, the Edaiken, the Iy’Ọba, and the Ezọmọ (Girshick Ben-Amos 1999, p. 68). The Ewu ivie would be worn along with the Odigba (coral bead collar).

The Ọba is the monarch of the Edo people and Kingdom. The current reigning monarch, Ọba Ẹwuare II, is the fortieth Ọba of the current dynasty, which is traditionally understood to have begun around 1170 AD ( ). Over the centuries, the role and conception of the monarch have shifted, and the Emwin Arre (royal treasures) and the visual language they carry provide important evidence for understanding these developments. Although Emwin Arhe served a variety of functions within court life and ritual, “their primary purpose was to glorify the godlike king and the history of the powerful empire” (Plankensteiner 2007, p. 25). Representations of the Ọba are therefore ubiquitous across Benin court arts and frequently occupy a central position within their visual language.

Representations of the Ọba can be recognised through a combination of characteristics, including his size, as he is usually depicted larger than other figures, and his position within compositions, where he may appear in front of or be supported by other figures, as in the Royal Triad motif. The Ọba is also distinguished by particular items of regalia, including the Oro projection from his crown, the distinctive beaded swag extending from his right hip, the Ewu ivie (coral-beaded shirt), and Ukpan obọ eva (crossed coral-beaded baldrics).

Since the early 20th century, scholars have sought to identify individual Ọbas represented on Emwin Arhe by analysing the regalia and other attributes of figures identified as monarchs, as well as the combinations of motifs and figures appearing on particular objects. Oral traditions and historical accounts, alongside European archival sources, have also played an important role in determining the identities of specific Ọbas (e.g., , ; ). Just as the institution of the monarchy developed and changed over time, so too did the ways in which Ọbas were represented by artists working within the royal guilds, including the Igun-Ẹrọnmwọn and Igbesamwan.

Enobare is the term used for the supporting figures who are typically depicted alongside the Ọba, holding his arms or hands as part of the Royal Triad motif. Their identities are interpreted variously: they may represent the Osa and Osuan, who support the Ọba during certain ceremonial contexts, or, particularly in representations dating to the 18th century, the Edaiken (crown prince) and Ezọmọ ( ).

Although many other members of the Benin royal court wore a variety of hats and forms of headwear, only the Ọba may wear the Ẹde (beaded crown). The Ọba must never be seen bare-headed, and successive Ọbas introduced different styles and types of crowns ( ).

Across different media and objects, Ọbas are depicted wearing various types of crowns, all elaborately crafted from coral beads. Some feature tall projections rising from the crown, known as Oro, while others have curved projections extending from either side of the head, known as the winged cap. The latter was introduced only in the 19th century, most likely by Ọba Osẹmwẹndẹ ( ). Depictions of Ọba Esigie on Ama-Ẹrọnmwọn (bronze relief plaques) show him wearing an elaborate crown decorated with large jasper or coral beads ( ).

The Ogho (ram) is associated with masculine and aggressive qualities, bravery and agility in Edo belief, as well as with conflict and trouble ( ). Due to these symbolic associations, the Ogho is one of the animals often used for sacrifice, particularly at the Ikẹgobọ (altar to the hand), as an offering associated with physical strength and power. Rams, particularly ram’s heads, are a common motif used to decorate the flanges of Uhunmwu-Elao (commemorative heads), as well as serving as the central decorative motif on pendant plaques. These Ogho pendant plaques are believed to have been worn by the Ọba, based on evidence from depictions of a figure interpreted as Ọba Ewuakpe ( ; ). According to Barbara Blackmun ( ), the Ogho head motif was one of the dynastic motifs that were revived during the 18th century. The widespread use of the ram’s head motif suggests connections with other southern Nigerian casting centres, such as Ife, Owo, and the Lower Niger Bronzes.

In addition to the ram’s head motif, two unusual aquamaniles in the form of whole Ogho figures were also cast by artists from the Igun-Ẹrọnmwọn.

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 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).

The Ẹkpẹn (leopard) is an animal that appears most often among the motifs decorating the Emwin Arhe (royal treasures). The Ẹkpẹn symbolises the valour and strength of the Ọba, as well as his political authority. The Benin people eulogise the Ọba as the ‘ẹkpẹn n'owa’ (leopard of the home).

When a hunter kills a leopard, he must say “ẹkpẹn n'oha” (I killed a bush leopard), as it is taboo to say that a hunter killed a leopard without specifying that it is a bush leopard, as otherwise this would “be tantamount to symbolically killing the king” (Nevadomsky 1988, p. 81). For this reason, leopards of the bush are called Atalakpa to distinguish them from those that represent the Ọba.
