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.

Hairstyles are used to determine a person's status in the society, as chiefs, common folks, chief's wives and the wives of the Ọba all wear different hairstyles. We have Okuku, Ikpe~okhokho, Idu~akpata

The Ahianmwẹ-Ọrọ, meaning ‘bird of prophecy’ in English, is a bird with a long beak believed to be a messenger of the spirit world. If it cries ‘OyaO’ (disgrace), it portends danger or disaster. If it cries ‘Oliguegue’ (be grateful), it portends good favour, fortune, or luck. If it persistently cries ‘OyaO, OyaO’ in front of someone, it is prophesying that the person should be cautious and should not undertake a journey, or should return home rather than continue. But if the bird cries ‘Oliguegue’ continuously, the journey will be favourable.

In 1515, as Ọba Ẹsigie passed through the gates of Benin on his way to fight the Attah (king) of Idah, the Ahianmwẹ-Ọrọ made discouraging sounds overhead, ‘OyaO, OyaO’, portending that disaster lay ahead. The Ọba ordered the bird to be killed and went on to win the war. He said, ‘Nẹ O gha yin Agbon, ghẹi daho Ahianmwẹ notiẹ oya’ (whoever wishes to succeed in life should not heed the bird of prophecy). On the Ọba’s triumphant return from battle, he commissioned the Igun-Eronmwon to make an image of the bird on the finial of a battle standard to remind it that the Ọba was not subject to the fate of ordinary spirits (personal communication, Patrick Oronsaye, 2022).

The identification of which bird the Ahianmwẹ-Ọrọ represents has been a subject of scholarly debate throughout the 20th century. Some have suggested that the bird is an African pied wagtail (Melzian 1937, p. 5), an ibis (Dark 1962, p. 46), possibly a kind of kingfisher (Ben-Amos 1976, p. 252), a hornbill (McCall 1975, p. 293), or, lastly, a white-tailed ant thrush (Nevadomsky 1988, pp. 76–77). In the case of the Ahianmwẹ-Ọrọ, however, Joseph Nevadomsky (1988, p. 77) posited that the exact species being represented was in fact less important. Instead, the aim was to “convey certain notions about the supernatural powers of the Ọba” and that the physical attribute (e.g., the long beak) was in fact the Ọba Ẹsigie’s casters’ way of seeking to “emphasise its vocal powers of prophecy, and, perhaps more importantly, the overcoming of these powers by the Ọba.”

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).

The Benin people use beads as one of their most important ceremonial body ornaments. There are coral and stone beads, which came mostly from long distance trade. The bead workers of Benin kingdom are called Enisen and they specialise in the art of bead making, particularly the royal regalia. Different types of beads are also worn for various ceremonies. The greatest honour anyone can get in Benin kingdom and from the Oba is to be decorated with a bead, the Ikele - a symbol of nobility.

Ẹyẹn (snakes) are among the most common animals depicted by Edo artists on the Emwin Arhe (royal treasures). The varied depictions of these reptiles suggest different snake species, including the Ikpin (python), Arhunmoto (puff adder), and Olose (red-black striped snake); therefore, here we use the generic term for snake: Ẹyẹn.

The identification of snake motifs and depictions as Ikpin, as well as the importance accorded to this species, is a subject of scholarly debate. Paula Ben-Amos (1976, p. 247) argued that the Edo admired the “stature, colouration and crushing power” of the python, which was in turn associated with Olokun. She went on to identify the brass figures of snakes that formerly adorned the roof of the palace, as well as several other snakes, as pythons. Joseph Nevadomsky (1988, p. 77) argued instead that the importance of the Ikpin had been overstated.

Some of these snake representations may in fact be the Arhunmwoto (puff adder). The first to suggest this was the German curator Felix von Luschan (1919) in his early research into the Benin royal treasures. Nevadomsky (1988, pp. 79–80) suggested that the large head, narrow neck, and rough scales are indicative of either the puff adder, a symbol of “material wealth, tribute, and gifts,” or the Gaboon viper.

Another kind of snake that may be depicted is the Olose (red-black striped snake). It has the praise name “king of the snakes” in Edo. Olose is also closely connected to the deity Olokun, both because of its attractiveness and because it inhabits wet environments such as forest streams, which in turn flow into rivers and the sea, where Olokun lives (Nevadomsky 1988, pp. 76–77). Although the exact meanings of these different snakes vary, they share the characteristic of being spiritually powerful creatures.

Representations of figures, often the Ọba, with an Ukhurhẹ (Ancestral Staff) in their right hand recur in a number of Emwin Arre (royal treasures), particularly those carved in wood as Agba (royal stools), cast in brass as part of Osogan (Osun staffs) and Ikẹgobọ (altars to the hand), and carved in ivory as Aken'ni Elao (carved tusks).

Ukhurhẹ are rattle staffs, usually made from wood, although brass examples are believed to have been owned by the Ọba. Ukhurhẹ were, and continue to be, commissioned when the paternal head of a family passes away as a way of commemorating them ( ). Following a ceremony in which they are installed on the family’s ancestral altar, Ukhurhẹ are typically lined up against the back of the altar and are used to communicate with ancestors and the spirit world. When depicted on the Emwin Arhe, Ukhurhẹ are usually held in the right hand of the Ọba, while an Ughavan (celts) is carried in his left hand.
