Ẹyẹn (snakes) are among the most common animals depicted by Edo artists on the Emwin Arhe (royal treasures). The varied depictions of these reptiles suggest different snake species, including the Ikpin (python), Arhunmoto (puff adder), and Olose (red-black striped snake); therefore, here we use the generic term for snake: Ẹyẹn.

The identification of snake motifs and depictions as Ikpin, as well as the importance accorded to this species, is a subject of scholarly debate. Paula Ben-Amos (1976, p. 247) argued that the Edo admired the “stature, colouration and crushing power” of the python, which was in turn associated with Olokun. She went on to identify the brass figures of snakes that formerly adorned the roof of the palace, as well as several other snakes, as pythons. Joseph Nevadomsky (1988, p. 77) argued instead that the importance of the Ikpin had been overstated.

Some of these snake representations may in fact be the Arhunmwoto (puff adder). The first to suggest this was the German curator Felix von Luschan (1919) in his early research into the Benin royal treasures. Nevadomsky (1988, pp. 79–80) suggested that the large head, narrow neck, and rough scales are indicative of either the puff adder, a symbol of “material wealth, tribute, and gifts,” or the Gaboon viper.

Another kind of snake that may be depicted is the Olose (red-black striped snake). It has the praise name “king of the snakes” in Edo. Olose is also closely connected to the deity Olokun, both because of its attractiveness and because it inhabits wet environments such as forest streams, which in turn flow into rivers and the sea, where Olokun lives (Nevadomsky 1988, pp. 76–77). Although the exact meanings of these different snakes vary, they share the characteristic of being spiritually powerful creatures.

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.

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.

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 Isẹ vbe ẹigho is a type of proclamation staff held by the Ọba during the two main annual ceremonies in the Edo calendar: Igue and Ugie Erha Ọba. Its form resembles that of the Ẹgogo (gong), but it has a longer handle and a distinctive horizontal cross at the base of the V-shaped upper section. In depictions on Emwin Arre (royal treasures), the Ọba alone carries the Isẹ vbe ẹigho, usually in his left hand, while holding the Ebẹn (ceremonial sword) in his right. Such representations appear on carved wooden Agba (ceremonial stools), Aken'ni Elao (carved ivory tusks), and cast-brass representations of the Ọba.

The staff is emblematic of the Ọba’s power and authority (Ben-Amos Girschick 2007, p. 158; ). Together with the coral-beaded regalia worn during these ceremonies, the Isẹ vbe ẹigho is understood to confer upon the Ọba the power to swear oaths and pronounce curses.

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).

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”.
