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 ( ).

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).

Ukpọn is the Edo term for cloth (Aigbe 1985, p. 55; Ọbazee 2025, p. 542) and is used here to refer to the wrappers or kilts worn by many of the figures depicted on the Emwin Arre (royal treasures). The cloth worn around the waist may be plain, but it is more commonly richly decorated with motifs associated with the monarchy, power, and wealth, such as the Ọba'nui (infinity symbol) and Uhunme Ikpotoki (Portuguese heads).

The Benin Kingdom was renowned for its textile production, both for local use and for trade ( ). Within the royal court, members of the Owina n’Ido produced ukhuen cloth for the Ọba and other members of the court, who wore it as wrappers during festivals and ceremonies ( ).

Alongside locally produced textiles, imported cloth was also an important commodity in the Benin Kingdom’s trade networks. Textiles were exchanged with neighbouring production centres, particularly Ijebu ( ), while European traders brought silks, woollens, linens, and cotton from Europe and Asia from the 15th century onwards ( ).

According to , this motif is known as Aghadaghada, a “play on the word ada,” meaning “crossroads.” The design appears as a background motif on a small number of Ama-Ẹrọnmwọn (bronze relief plaques) and is associated with Olokun and the period of close contact between the Benin Kingdom and the Portuguese Empire during the reigns of Ọba Ọzọlua, Ọba Ẹsigie, and Ọba Orhogbua ( ). At the time of Ben-Amos’s research, the same symbol was drawn in chalk at the centre of Olokun shrine courtyards in Benin City. described the design more literally as a “circled cross” and suggested that the Ama-Eronmwon bearing this background motif may have been cast by a particular ‘master’ or member of the Igun-Ẹrọnmwọn.

More broadly, the cross, with its four points, references the number four, which has significance in Edo belief: the Edo week consists of four days, and each day is divided into four parts ( ). Other cross forms are treated as distinct motifs and are discussed separately under Uman-Ague (equal-armed cross).

Ikoro (armcuffs) are made from different materials using different techniques, including brass sheet, cast bronze, and ivory. They were crafted by different guilds depending on the material used: artists of the Igun-Ẹrọnmwọn cast them in brass or hammered and incised them from brass sheet, whereas artists of the Igbesamwan carved ivory Ikoro. Ikoro were made in different qualities, from rather simple examples with abstract geometric decoration to finely carved ivory examples with brass or copper inlays. Ikoro are worn in pairs on both forearms by chiefs and the Ọba during ceremonies and festivals. Figures depicted on the Emwin Arhe (royal treasures) are often shown wearing such pairs.

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).
