Akọn Ẹkpẹn are necklaces or neck ornaments made of strung leopard’s teeth. They are worn by figures to signify their high rank and military prowess, as well as by their leaders, the Ezọmọ or Iyasẹ. They are often worn alongside quadrangular Ẹroro (bells) and Ohian Ẹkpẹn (leopard tunics).

The Akọn Ẹkpẹn is clearly and profoundly related to the symbolism of the Ẹkpẹn (leopard) and its association with the Ọba (king), who is metaphorically referred to as ‘ẹkpẹn ne owa’, the ‘leopard of the home’. On the other hand, the Ẹkpẹn is often referred to as the ‘king of the bush’, embodying ferocity, aggression, strength, and leadership—qualities attributed to the Ọba. This intricate link between the leopard, the monarch, and his military leaders reinforces the complex hierarchy and spiritual authority central to Benin’s courtly art.

Ẹroro (bells) frequently appear as ornaments worn by figures depicted on the Emwin Arhe, particularly on Ama-Eronmwon (bronze relief plaques) and Aken’ni Elao (carved tusks). These Ẹroro are most commonly quadrangular in form or, less commonly, cylindrical with rounded tops. Quadrangular Ẹroro worn around the neck are often part of the attire that indicates that figures can be interpreted as warriors, alongside the Akọn Ẹkpẹn (leopard tooth neck ornament) and the Ohian Ẹkpẹn (leopard tunics).

Hornblower and flute-player figures recur frequently in the visual language of Emwin Arhe (royal treasures), particularly on Ama-Ẹrọnmwọn (bronze relief plaques) and Aken’ni Elao (carved tusks). Horns and flutes made from ivory and brass have long been used in the Benin Kingdom, with ivory instruments continuing to be used today.

Akohẹn are the largest type of horn and were used exclusively by the Ọba’s retainers before sacrifices in the palace. The Ikpakohẹn is a specialist hornblower responsible for playing the ivory Akohẹn, a role introduced during the reign of Ọba Eresonyẹn. According to Ọba Akẹnzua II, a group of six hornblowers from Use played these horns during Ugie (in Bradbury 1957, B.S. 85). Another type of horn, the Oko, was used by Ebo “to call witches and wizards to come to the crossroads”.

Ọba Akẹnzua II (in Bradbury 1957, B.S. 85) also described the Eziken, a thin, side-blown fife or flute made from calabash or ivory. These instruments were played by members of the Ikpeziken, the guild of royal flute players, who performed as part of musical ensembles during ceremonies such as Ugie.

Warrior chiefs or commanders are often depicted on the Emwin Arhe, in particular the Ama-Ẹrọnmwọn (bronze relief plaques) and the Aken’ni Elao (carved tusks). Edo artists often represented Warrior Chiefs using attire such as Ohian Ẹkpẹn (leopard tunics) and Akọn Ẹkpen (leopard’s tooth neck ornament), which they are often shown wearing during ceremonial occasions such as Isiokuo. Warrior chiefs, or the attendants who often accompany them, may also carry an Asa (shield) or an Ẹbẹn (ceremonial sword). Additionally, a number of representations in both brass and ivory show War Chiefs riding on horseback, an indication of their social status, military rank and prowess.

In the Edo military hierarchy, there are four key titles for those bestowed with the highest rank, namely the Iyase or the Generalissimo who was second in command to the Ọba. Next in line is the non-hereditary title of Ezomo, part of the Uzama Nihinron. Next in command, is the Edogun, commander of the Ekaiwe, made up of the sons of the Ọba’s daughters. The Edogun would brief the Ọba on war plans, strategies and tactics, the general appraisal of military strength and also had the role of declaring war by displaying the Asa (battle shield) and then marking the end of war by returning the Asa. The Ekegbian, head of the Isienmwenro (royal guards in the Ọba Palace and with detachments in most Edo towns), was next in the chain of command. Only the Ọba could command the Ekegbian to mobilise the Isienmwenro for battle.

The Iyase can often be identified by the rounded bell-shaped headwear artists depict him wearing across different types of Emwin Arre, from Ama-Ẹrọnmwọn, to Aken ni’Elao, and carved representations on idiophone staffs. However, identifying the Ezomo is less easy to identify, although figures wearing a peaked helmet and the usual symbols of military commanders have been identified as representations of the Ezomo. )

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.

Akohẹn, or ivory horns, are played by members of the Ikpakoen (guild of ivory hornblowers), while Oko, or flutes, are played by members of the Ikpeziken (guild of royal flute players). Among the Emwin Arhe (royal treasures), Oko and Akohẹn are usually depicted being played by brass-cast figures representing members of these guilds, and also appear on Ama-Ẹrọnmwọn (bronze relief plaques), Aken'ni Elao (carved altar tusks), and Urhotọ (altar tableau).

Today in Benin City, when a public procession leaves the palace, a court official may sound side-blown horns made from ivory. Historically, these instruments were also used during warfare, where they were played alongside Ema (drums) and Ẹroro (bells), producing a “cacophony of sound” whose “[t]he psychological effect of the barrage of noise magnified the size of Benin’s forces”.

Some Oko/Akohẹn were also cast in brass by members of the Igun-Ẹrọnmwọn. However, these brass examples are understood not to have been functional instruments and could not have been blown like their ivory counterparts.

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. 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.

Many different kinds of Ẹrhu (headwear) are worn by the various figures depicted in the imagery of Benin royal artefacts. Through comparisons with ceremonial regalia still worn by chiefs and members of the royal court, including the Ọba himself, some Ẹrhu have been used to identify the different figures depicted. For example, the conical hat worn by high-ranking town chiefs as part of the pangolin regalia, still worn at ceremonies, is also visible on figures on some Ama-Ẹrọnmwọn (bronze relief plaques). Other examples include the distinctive bell-shaped helmet associated with the Iyasẹ. Figures who wear a shallow-brimmed hat and a cross have been identified as Ewua or Ohensa priests.

Different kinds of helmets and headwear were worn by warriors, reflecting the many different ranks and roles in the army at any given time, as well as developing trends that were in turn represented on Emwin Arhe created at different points in time. Warrior figures wearing helmets covered in cowrie shells were carved on the Aken'ni Elao (carved tusks) (Blackmun 1984, p. 330), yet on the brass Ama, warriors are sometimes depicted wearing helmets made from crocodile hide or horsehair with a front plate (Osadolor in Plankensteiner 2007, cat. no. 238, p. 457). Helmets made from horsehair with a front plate are one of the more common types represented on the Ama-Ẹrọnmwọn, and the demand for black horse tails was noted by both Portuguese and British traders during the late 17th and 18th centuries (Osadolor in Plankensteiner 2007, cat. no. 238, p. 457). Other warriors depicted on Ama-Ẹrọnmwọn wear helmets with a rounded top, chinstrap, and sometimes also a feather tucked into the left side. These types of headwear are known as Ẹrhu Iyokuo.

Attire worn for battle also differed from that worn for ceremonial occasions, such as the pointed headwear worn in combination with an ornate leopard-head tunic by war chiefs. Depictions of figures wearing this attire on brass Ama-Ẹrọnmwọn (bronze relief plaques) have been interpreted as representing the war chiefs’ participation in the war-ritual Isiokuo festival (Osadolor in Plankensteiner 2007, cat. no. 238, p. 457).

Another distinctive form of headwear is that worn by figures identified as leopard hunters on the brass Ama-Ẹrọnmwọn (relief plaques). These large helmets cover almost all of the leopard hunters’ faces except for their noses, eyes, and upper lips, and are made of an unusual material that remains unidentifiable (Plankensteiner 2007, cat. nos. 68–69, p. 322).

European figures are also portrayed with distinctive hats, such as Portuguese three-cornered hats. These depictions reflect the artists’ keen observation and highlight the impact of European trade and military assistance (Ezra 1992).

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.

Uhanbọ (bows) and Ifẹnmwẹ (arrows) were produced by members of the Iwifenmwen (guild of archers and manufacturers of poisoned arrows). Arrows, particularly poisoned arrows, were used in warfare. When depicted on Emwin Arhe (royal treasures), Uhanbọ and Ifẹnmwẹ are believed to represent Ake, the deity of archery. According to Aisien (in Plankensteiner 2007, cat. no. 218, p. 438), Ake was an expert marksman who lived during the reign of Ọba Ẹwuare (c. 1440–1473 AD) and is credited with inventing the poisoned arrow used in hunting and warfare.

The frequency with which Ọkhọn Okuo (Benin warriors) are depicted in Emwin Arre (royal treasures) reflects the importance of the army and military to the Kingdom, as well as the role of royal art as an archive in which artists from the palace guilds recorded important people, events, and institutions. The army was organised into a number of regiments, with soldiers grouped according to the weapons they used, including archers, swordsmen, crossbowmen, and spearmen.

Warrior figures are frequently shown carrying weapons such as Asa (shields), Asoro (spears), warfare swords such as the Umozo or Ọhọ (executioners’ or warfare swords), Uhanbọ (bows), Ẹkpẹde (crossbows), and Ifẹnmwẹ (arrows), which were sometimes poisoned, as well as Osisi (firearms). Their dress also provides important indications of their military role. On both the Aken'ni Elao (carved tusks) and Ama-Ẹrọnmwọn (bronze relief plaques), warriors are depicted in a relatively standardised form, typically wearing an Ohian Ẹkpẹn (leopard tunic), Akọn Ẹkpen (leopard’s tooth neck ornament), an Ẹroro pendant around the neck, and the Uko ugbo-ohamwen (fortified chest band).

Differences are particularly apparent in the warriors’ headwear, both between individual figures and between representations on Aken'ni Elao and Ama-Ẹrọnmwọn. On the Ama - Eronmwon, the most common forms of headwear are crocodile-hide helmets and horsetail helmets with a front plate. On the Aken'ni Elao, some warriors wear double-horned helmets, while others wear simple rounded hats or helmets. The most frequently represented warrior type on the tusks, however, wears a helmet with cowries sewn onto a front panel.
