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.

The Ititi ako is a cluster of coral beads, usually three or four, attached to a pin and used to embellish the royal crowns on Uhunmwu-Elao (commemorative heads) and Uhunmwu-Ẹkuẹ (pendant masks). These bead clusters are also known as star beads, which indicate the prosperous destiny of an individual or wearer. Apart from enhancing the appearance of the wearer, they also represent the individual’s high social status. Judging from their presence on a variety of head sculptures, both men and women wore Ititi ako.

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.

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.

The Ukpan obọ eva (coral-bead crossed baldrics) were worn as part of the ehaingbehia, the full ceremonial regalia, by only high-ranking members of the palace, including the Ọba himself, the Iy’Ọba, the Edaiken, and the Ezọmọ (Ben-Amos 1999, pp. 68, 141; Osadolor in Plankensteiner 2007, cat. no. 70, pp. 322–323).

Ughavan (celts) are often seen as part of the decoration along the flanges of the Uhunmwu-Elao (commemorative heads), alongside trunk hand, leopard, or cow’s head motifs, or held in the left hand of the Ọba on the Ikẹgobọ (altar to the hand). This imagery has a particular meaning: when the Ọba holds the Ughavan in his left hand, it is said to be known instead as isauan (faeces of thunder) and is believed to “increase the potency of a curse or a blessing” ( ).

These motifs are sometimes interpreted as Uzo (antelopes) but also as Emila (cows). Both animals share certain characteristics, being regarded as physically beautiful and peaceful creatures. Some Orhiẹvbẹ (kola-nut bowls) take the form of an antelope head with its horns grasped by a pair of hands, a gesture that symbolises the right of humans to sacrifice antelopes and cows with impunity (Ben-Amos Girschick 2007, cat. no. 88, pp. 339, 341).

Uzo primarily symbolise beauty, docility, and their status as permissible sacrificial animals, reinforcing themes of human control over nature and the rituals that underpin social and spiritual order.

Ikharo are linear keloid markings depicted on the forehead of Uhunmwu-Elao (commemorative heads) in groups of three or four above each eye. The exact meaning of Ikharo is debated; some have argued that they relate to the gender or tribal identification of the person on whom they are depicted. For example, has argued that they were worn only by men; however, their use in depictions is not consistent with this, and the Iy’Ọba are also shown wearing them. argued that they are instead a stylistic feature employed by artists that varied over time.

The naming of these markings differs between publications. For example, describe these markings as “agbaguda n'ehae”, which they write translates literally as “blades of the forehead”. However, later went on to call these “ikharo”, as used here. referred to these forehead markings as ikharo, meaning “tribal mark [of eye]”.
