Iwu are facial and body markings (scarifications) that were historically worn by Edo men and women. However, since the 1960s, the practice has been nearly extinct (Aisien 2011). In the past, Iwu were used as a way of proving that one was an Edo citizen, and the ceremony of having Iwu completed was an important rite of passage for men and women. The Osiwu, who also practised circumcision and other surgical procedures, would carry out the procedure of adding Iwu. There are different types of Iwu: ‘blades’ worn on the torso (Iwu-eko), and those worn on the face, such as Ikharo (three or four markings above the eyebrows), Irho (two narrow ‘blades’ worn on each cheek), Ovbihue (nasal ‘blades’), Ovbi-agbanmwen (chin ‘blade’), and Igho-okpa/Ukpgho (three forehead ‘blades’) (Aisien 2011, p. 22).

The number of Iwu also varied depending on the identity of the person wearing them. For example, royal men would wear six ‘blades’ on their torso, whilst men who were not royal would wear seven ‘blades’. Meanwhile, the Ọba’s female children would wear fifteen ‘blades’, and all other women would wear sixteen (Aisien 2011).

Spherical rattles made from gourds and covered with nets, known as Ukuse, are held in both hands by some figures depicted on Emwin Arre (royal treasures). Barbara Blackmun ( ) noted that these rattles are unusually spherical and smaller than the gourd rattles used today, suggesting that they may have had a particular significance. The Ọba is sometimes depicted holding such a rattle while “wearing an empowering necklace and his most elaborate crown.” On this basis, Blackmun argued that the “spherical rattle of diminutive size and shape may have been employed to heal, or to bring about other transformation” ( ).

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.

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]”.
