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”.

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 fist motif—particularly a clenched fist with an extended thumb—carries significant symbolic weight. It is central to the cult of the hand, a major aspect of Edo religion that focuses on an individual’s ability to achieve success through their own actions, skills, and enterprise ( ). This cult is primarily observed by those who have already attained considerable wealth or status, including hunters, warriors, and craftsmen.

The fist symbolises physical prowess and strength, denoting the individual’s might and accomplishment ( ). The hand is credited with enabling the accumulation of great riches and high status. This is sometimes linked to the idea that wealth results from both personal effort and the favour of Olokun, the god of wealth. On Ukhurhẹ (ancestral staffs), a clenched fist or hand grasping a mudfish signifies royal or chiefly authority. The image of a hand holding a coiled mudfish can also illustrate the Ọba’s formidable power to “cast and then release a curse” or to “set up obstacles and remove them” ( ). The fist is sometimes accompanied by other motifs symbolising strength, chieftaincy, and longevity, such as tools like the hammer and pliers or feathers of the vulturine fish eagle ( ). The fist motif is frequently depicted on Aken'ni Elao (carved tusks), on wooden Ikẹgobọ (altars to the hand), and on Ukhurhẹ.

This oval-shaped bead with faceted sides is known as the Ivie okpagbaru or Ivie Ewuare (the ‘royal bead’ or ‘Ewuare bead’). The association of Ọba Ewuare with this bead is based on a story in which Ewuare took beads from the deity Olokun, sanctifying his royal position and, in turn, receiving the title ‘Lord of the Land’, in contrast to Olokun’s title ‘Lord of the Sea’ (Omomo of Enisen in Blackmun 1990, p. 65). The Ivie okpagbaru/Ivie Ewuare is a distinctive motif that can be used to identify representations of the Ọba.

Due to the association of beads with Olokun, it is unsurprising that this bead has come to symbolise wealth when used to decorate Emwin Arhe (royal treasures) (Blackmun 1984, p. 59). Paula Ben-Amos (1999, p. 64) associated the bead with a different narrative and the name ‘One Bead Does Not Go around the Neck’. Ben-Amos suggests that the bead is in fact the one that was fought over by Ọba Ẹsigie and his brother Aruanran when they struggled for the right to the throne in the early 16th century.

Ẹgogo (gongs) hold significant importance in Benin art and ritual, serving as powerful instruments with both practical and symbolic roles. Ivory gongs, especially “double-bell” types, were highly prized and reserved for the royal court, particularly those made entirely of ivory, which were used exclusively by the Ọba. The whiteness of ivory Ẹgogo symbolises purity and peace and is linked to sacred Orhue (white kaolin chalk) and the deity Olokun (Blackmun 2007, cat. no. 60, p. 315).

When depicted in the imagery of the Emwin Arhe (royal treasures), Ẹgogo are usually held by figures such as the Ọba or high-ranking chiefs, illustrating their historical and ongoing use as idiophones during ceremonies and festivals. The Ọba dances with an ornately carved ivory Ẹgogo during the Emobo festival, which takes place three days after the Iguẹ festival (Ben-Amos 1995, p. 108).
