Ebe Amẹ refers to a wide variety of plants, particularly the leaves of the water fern or river leaf, found in riverine areas of southern Nigeria ( ). Artists from the Igun-Ẹrọnmwọn used these as a decorative motif in the background of most Ama-Ẹrọnmwọn (bronze relief plaques). The petals of the Ebe Amẹ, like the points of the ἀghàdàgháda (crossroads), represent the four cardinal directions: north, east, south, and west. The number four plays a foundational role in the Edo calendar, which is structured around four market days ( ).

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).

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).

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.

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”.

Warrior chiefs or commanders are often depicted on the Emwin Arhe, in particular the Ama - Eronmwon (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 (Osadolor in Plankensteiner 2007, cat. nr.62, p.316; cat. nr.244, p.459).

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 (Osadolor 2007, pp.78-9).

The Iyase can often be identified by the rounded bell-shaped headwear artists depict him wearing across different types of Emwin Arhe, from Ama - Eronmwon (bronze relief plaques), 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 (Blackmun in Plankensteiner 2007, cat. nrs. 118-9, p.363)

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 (Nevadomsky 1988). 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.

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 Umozo is a type of sword with a short, broad, and curved single-edged blade that was used by warriors during warfare (Bradbury 1973, p. 260; Osadolor 2001, p. 109). According to Benson Osadolor (2001, p. 109), it is remembered in Benin City as one of the oldest kinds of weapons used in warfare and “was better for the attack than defence”.

These motifs are known as Uhunmwu Ikpotoki in Edo, which translates as ‘Portuguese head’ in English. Portraits of Portuguese men, featuring only their heads and sometimes their shoulders, were used by artists as motifs on the Emwin Arhe (royal treasures), in particular on the Ama-Ẹrọnmwọn (bronze relief plaques) and Aken'ni Elao (carved altar tusks). Also included here are a series of two or three conjoined spirals, which are interpreted as abstract forms of this motif.

One of the earliest suggestions that many of the European figures depicted on objects were Portuguese was made two years after the 1897 British Colonial Military Campaign on Benin City by the British Museum curators Charles Hercules Read and Ormonde Maddock Dalton (1899, p. 19), based on testimony from seven chiefs in the aftermath of the military campaign. The long, straight hair, beards, and domed hats together led to the identification of these representations as Europeans (von Luschan 1919, pp. 54–57; Ezra 1992, p. 246).

When included within the visual imagery of the Emwin Arhe, the Portuguese are associated with the new Atlantic trade and the consequent wealth that emerged following first contact with the Portuguese in the late 15th century. For this reason, Portuguese heads are also often associated with the sea deity Olokun. Eisenhofer (2007, p. 59) argued that the Portuguese figures and heads as motifs on the royal treasures are symbols of the king’s power: “these depictions of foreigners helped to build and strengthen the king’s image.”

When incorporated into the design of the Ama-Ẹrọnmwọn (bronze relief plaques), Curnow (1997, p. 48) instead argued that these motifs could in fact indicate events that took place during Ọba Esigie’s reign. Ọba Esigie is associated with the Portuguese, as they became increasingly important during his reign, assisting with battles against the Igala from Idah, bringing Catholicism to Benin, and introducing weaponry such as guns and cannons, which were instrumental in the expansion of the kingdom.

The Uki (moon) is said to be associated with coolness, peace, and joy and to be more important than even Owẹn (the sun) ( ; ). The behaviour and nature of the moon were and are studied by the Iwoki, the guild of astrologists and meteorologists established by Ọba Esigie (c. 1504–50).

The Uki is usually depicted in crescent or half-moon form and appears on some of the Ama-Ẹrọnmwọn (bronze relief plaques), sometimes on its own as a corner motif and at other times as part of compositions with figures identified as being part of the Iwoki. Crescent forms of the moon are also used as part of the motifs decorating textiles and clothing worn by figures.

Ẹguẹn are worn by the Ọba and chiefs as part of their Ehaengbehia, the full regalia worn during special ceremonies. Ẹguẹn are worn around the ankles or calves and can be made from beads, ivory, brass or even iron. A separate category, called Elubase, refers to those which have integrated rattles or crotal bell attachments, however both are described as anklets in English.

As early as 1899, Read and Dalton commented that the anklets worn by figures shown on plaques were a signifier of high rank. Today, anklets continue to signify social status, with the Ọba wearing many ivory and coral anklets stretching up his calves as part of his ceremonial regalia (Okpokunu, Agbontaen‐Eghafona & Ojo, 2005, p.162[106]). However, anklets were not the preserve of the Ọba alone, and different kinds and quantities were worn by other members of the royal court and Edo people. For example, Flora Kaplan (2006, p.85[107]) described a photograph of Iy’Ọba Aghahowa N’Errua, who took her title in 1981, in which she wears coral anklets as one of a number of insignia of her newly invested high rank. In contrast, brass anklets would be worn by young male attendants to the Ọba (see attendant figure), such as sword bearers or Emada pages (Kaplan, 2006, p.90[107]).
