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.

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 ( ).

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 ( ).

Ikan Aro are two linear markings in the centre of the forehead, located in between the eyes. These are usually inset with iron on depictions otherwise made of brass, bronze, ivory or wood.The use of iron was significant due the association of this metal with Ogun, who is god of iron and metal. These markings appear on both men and women, however are a common feature of representations of Iy'Oba Idia. Flora Kaplan (1993, 59) argued these are not tattoos, unlike the Ikharo. According to Nevadomsky (1986, 42), these incisions "signify determination, firmness, resolve, or even maturity". Kaplan (1993, 59) has also made a link between these markings and oral history told to her by Oba Erediauwa describing the events leading up to Idia (before she was Iy’Ọba) becoming the wife of Ọba Ozolua, whereby her parents tried to disfigure her to “repel” the Ọba. According to this history, the Ọba “sensing something was wrong”, called his doctors to intervene and treat her quickly, and as so she still became his wife.

Figures wearing a headdress with a single protrusion from the crown of the head, known as the Oro, are found only among the Ọba and a select category of palace dignitaries whose ancestors originated in ancient Ile Ife ( ; Ọbazee 2025, p. 407). Only the Osa and Osuan, custodians of the Uwen and Ora deities, as well as members of the Emuru, who are responsible for the care of Iru vessels, may wear a headdress with the Oro. The identification of different figures is therefore interpreted based on the combination of the Oro with other items of regalia. Artists in the Igun-Ẹrọnmwọn and Igbesamwan depicted figures with the Oro on Ama-Ẹrọnmwọn (bronze relief plaques) and Aken'ni Elao (carved tusks), respectively. The Oro would either be made of coral beads as part of the crown or headdress, or be woven from itoto fibre ( ).
