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 ( ).

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 ( ).

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 ( ).
