Ọyanyan (horses), along with their riders, are significant motifs in the visual language of the Emwin Arhe (royal treasures), appearing across various media and periods. Although the Benin Kingdom lies in the tropical region of West Africa affected by the tsetse fly, according to oral tradition, a small, stocky breed of horses introduced via trade routes from Nupe and Hausa was known in the kingdom from the 13th century (Dolz in Plankensteiner 2007, cat. no. 215, p. 434).

In 1505, King Manuel of Portugal sent a horse, alongside other luxurious gifts such as satin and Indian silk, to one of the Ọbas, most likely Ẹsigie, as a gift (Ryder 1969, p. 41). An account believed to have been written by the Dutch traveller Dierick Ruiters in 1602 described how he travelled from the port of Ughoton to Benin City on horseback (Blackmun in Plankensteiner 2007, cat. no. 138, p. 367). In the same account, Ruiters also described how the Ọba and his courtiers rode on horseback as part of ceremonial processions (Blackmun in Plankensteiner 2007, cat. no. 221, p. 441). A scene of this kind is also featured in the view of the city of Benin in Olfert Dapper’s Description of Africa (1668).

Ọyanyan therefore embody themes relating to military power, foreign interaction, and royal authority (Nevadomsky 1986), as well as “dignity and achievement” (Curnow in Plankensteiner 2007, cat. no. 115, p. 351).

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.

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).

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.”

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 Benin people use beads as one of their most important ceremonial body ornaments. There are coral and stone beads, which came mostly from long distance trade. The bead workers of Benin kingdom are called Enisen and they specialise in the art of bead making, particularly the royal regalia. Different types of beads are also worn for various ceremonies. The greatest honour anyone can get in Benin kingdom and from the Oba is to be decorated with a bead, the Ikele - a symbol of nobility.

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”.

The Ohian Ẹkpẹn is a significant ceremonial garment in Benin royal court art, primarily associated with warriors and military officials, underscoring their delegated authority and ferocious skill as warriors (Ben-Amos 1995, fig. 93).

The leopard tunic is typically made from leather and cloth decorated to imitate leopard skin, usually with the face of a leopard emblazoned on the chest using appliqué. An Akọn Ẹkpẹn (leopard tooth neck ornament) and quadrangular Ẹroro (bells) are often worn on top of the Ohian Ẹkpẹn. This tunic would be worn by the Ọba’s military chiefs (Blackmun 1984, p. 323).

In historical Benin, the Ọba held the exclusive right to distribute leopard skins to those officials to whom he delegated the power to take human life. This made the leopard tunic a potent symbol of delegated authority over life and death. Osarhieme Benson Osadolor (in Plankensteiner 2007, cat. no. 244, p. 459) recalled an Edo proverb: “It is the head of the leopard that accomplishes things for the leopard,” which is particularly significant for warrior chiefs, as this proverb indicates that the Ọba, known as the “Leopard of the Home,” relied on them to carry out his military campaigns.

Asoro (spears) were used as weapons in battle and for hunting ( ; Ọbazee 2025, p. 37). According to , there were two types: long and short. Figures holding Asoro are often depicted on Ama-Ẹrọnmwọn (bronze relief plaques), sometimes in battle scenes and at ceremonies and festivals.

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).

Asa (shields) are a crucial attribute of warriors and warrior chiefs, forming part of their ceremonial and battle attire as represented on the Emwin Arhe (royal treasures). Asa were usually made from elephant or crocodile skin and used by warriors for protection during hand-to-hand combat (Osadolor 2001, p. 102). Interestingly, the form of Asa depicted on historic royal artefacts differs from those found in museum collections today, reflecting changes in shield shapes and designs over time.

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.

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.

In the riverine area surrounding Benin City, there are two types of crocodile. The Ẹghughu, known in English as the dwarf or bush crocodile, is believed to be more docile ( ; Ọbazee 2025, p. 133). The second type is the Àgbákà, the aggressive Nile crocodile ( ; Ọbazee 2025, p. 11).

Crocodiles are one of the important animals represented in the historical Emwin Arhe, and they are known as Olokun’s guards or the “policemen” of the waters. The powerful and ferocious qualities of these animals might explain why warrior figures are often depicted wearing Uhunmwu-Ẹkuẹ (pendant masks) in the shape of crocodile heads on Ama-Ẹrọnmwọn (bronze relief plaques) ( ). Olokun devotees use crocodiles as sacrificial animals in offerings during the worship of Olokun.
