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.

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.

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 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).

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.

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.

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).

This motif of an Ọba with legs represented as two mudfish is often interpreted as Ọba Ohẹn, who reigned c. 1334–1370. According to oral traditions, Ohẹn suffered from paralysis of the legs and unsuccessfully attempted to conceal his condition from the chiefs and members of the royal court. The Iyasẹ Emuze eventually hid in the Ọba’s chambers to discover his secret ( ). When Ohẹn discovered this, he ordered the Iyasẹ to be executed. However, the people learned of the order and turned against the Ọba. According to the tradition, they plotted to kill him ritually by digging a hole beneath his throne and stoning him with Orhue (white kaolin chalk) when he fell into it ( ; ).

Not all representations of an Ọba with mudfish legs, however, are understood to refer to Ohẹn. Variations in the objects and animals carried by the figure are thought to indicate different meanings ( ; ). Members of the Igbesamwan and Igun-Ẹrọnmwọn have emphasised the significance of these accompanying motifs (Blackmun 1984, pp.249–255). When the mudfish-legged Ọba is shown holding aquatic creatures such as crocodiles, for example, the image has been interpreted as a “cosmological image” representing the correspondence between the two monarchs: the Ọba of Benin, ruler of the land, and Olokun, ruler of the waters ( ). By contrast, representations in which the Ọba holds swords or staffs have been interpreted specifically as depictions of Ọba Ohẹn.
