Metal, Pottery, Calabash and Leather
The smith and his god, the paired brass figures that carried the authority of the Ogboni society, the women who built pots without a wheel, the carved and burnt calabash, and the leather trades of Ilorin and Oyo.
Most of what a Yoruba household used was made by specialists in a small number of trades, each with its own guild, its own patron deity and its own gender rule. The smith worked iron under Ògún and stood slightly apart from ordinary society because of what he did. Brass casters made the paired figures that carried the authority of the Ògbóni society, the institution that could check and if necessary end a king. Women built pots without a wheel, including the great sunken pots that held the indigo. Calabash carvers at Ọ̀yọ́ scraped, incised and burned designs into gourds. Leatherworkers at Ìlọrin and Ọ̀yọ́ made saddlery, sheaths and amulet cases. None of these was a village sideline; in the nineteenth century they were all sustained by palace patronage.
Ògún and the smith
Ògún is the òrìṣà of iron, and by extension of war, hunting, clearing, oath-taking and every trade that uses metal, which today includes drivers and mechanics. The religious treatment of Ògún belongs to the òrìṣà section. What belongs here is the smith.
The alágbẹ̀dẹ is literally the one of the forge, from agbẹ̀dẹ, smithy. His position is dual in the way the smith's position is dual across West Africa: indispensable, because he makes the hoe, the cutlass, the weapon and the iron of Ògún's own shrine, and simultaneously set apart, because converting ore and scrap into metal is a transformative act understood as powerful and dangerous. Smiths form lineage guilds under their own head, keep their own Ògún obligations, and the smithy itself functions as a shrine site. Oaths sworn on iron have been accepted in Yoruba courts, colonial courts and modern Nigerian courts, and that continuity is a direct survival of the smith's ritual position.
One of the standard descriptions of Ògún has him wearing a red cap, understood as the glow of the forge and the transforming power made there .
The archaeology, stated carefully. The West African iron-working record includes very early dates, and they are routinely misapplied. The dates around 2000 BCE at Lejja and 750 BCE at Opi, both in the Nsukka area, are Igbo sites, not Yoruba, and the earliest of them is itself contested within African archaeometallurgy . They should not be transferred to Yorubaland.
The directly relevant Yoruba evidence is from Modakẹ́kẹ́ at Ifẹ̀, where Ige and Rehren analysed bloomery slags and found a skilful smelting operation extracting close to the maximum recoverable iron from the ore, working a mixed charge of limonite iron stone with an ilmenite-rich black sand . Deliberately mixing two ore sources of different character is a fluxing decision, not naive practice; it indicates a smelting tradition that understood what it was doing with slag chemistry. This is a technical finding from laboratory analysis and it is one of the more solid pieces of evidence for indigenous Yoruba metallurgical competence.
Brass, and the ẹdan Ògbóni
Brass in Yoruba use is not the same material as iron either practically or symbolically. It does not rust. That single property is the basis of its meaning.
The object. The ẹdan Ògbóni, called ẹdan Òṣùgbó among the Ìjẹ̀bú and Ẹ̀gbá, is a pair of brass figures, one male and one female, usually cast onto iron spikes and joined at the top by a brass chain . It is cast by lost wax over the iron core.
How it is used. It is worn as an emblem of office, the chain passing behind the neck so that the two figures hang forward against the wearer's chest . It is given to initiates as part of the process that purifies them and connects them to the earth . It is planted point-down in the ground. It is sent as a summons and a warrant: an ẹdan delivered to a person is a call from the society that cannot be refused. And it is used in judicial oath.
What it means. The pairing is doctrinal. The male and female figures are read as the attachment of the sexes in procreation and in a balanced society, as the founding couple of a community, and as the necessity of male and female cooperation . The figures resemble Onílẹ̀, the owner of the earth, in male and female forms . Onílẹ̀, literally owner of the house or land, is the earth deity who is the Ògbóni society's ultimate authority.
The material argument. Casting brass over an iron rod signifies the union of the magical forces associated with the two metals, and the non-rusting character of brass symbolises immortality, the desire for longevity and continuing well-being . So the object is an argument in metal: brass, which is Ògbóni, earth, permanence and in this pairing the female, fused with iron, which is Ògún, cutting force and the male. It is not a decorated object; the material choice is the content.
Why this matters politically. The Ògbóni or Òṣùgbó society held considerable political, judicial and religious power in precolonial Yorubaland . It is the institutional check on the ọba: it controls the earth on which the town stands, tries capital cases, and in the classical Ọ̀yọ́ and Ẹ̀gbá constitution can require a king's suicide. Its inner council is the Ìwàrèfà, six senior titles. The ẹdan is that authority in portable form, which is why it functions as a summons. The terminological split by region, Ògbóni in Ọ̀yọ́ and Ẹ̀gbá usage, Òṣùgbó among the Ìjẹ̀bú, is worth knowing because the literature uses both.
The Adúgbólógè workshop at Abẹ́òkúta, treated in the wood sculpture file, produced Ògbóni material as its principal line, which shows that carving and casting served the same institution.
Pottery
The material and the terms. Amọ̀ is clay and by extension pottery. The named forms recorded in the Ìlọrin corpus include àmù, the large water pot or cooler; ìṣáasùn, the cooking or soup pot; ìkòkò, the generic pot, which specialises as ìkòkò agbo for herbal decoctions and ìkòkò aró for the indigo vat; orù, a pitcher, also used for herbal preparation; ape, an open-mouthed bowl; kólò, the sealed pottery savings box that has to be broken to retrieve what is in it; agbada, a fryer; and fìtílà, the clay oil lamp, a word taken from Arabic fatīla, wick .
Technique. Yoruba pottery is hand-built and there is no potter's wheel. The potter coils, or draws a lump of clay upward around a fixed or mould-supported base, then beats the wall thin with a paddle against an anvil stone held inside, then scrapes and burnishes the surface. The pot is dried in the sun and open-fired in a bonfire of grass, wood and old sherds rather than in a kiln, which is why Yoruba pots carry the characteristic irregular fire-clouding rather than an even colour. After firing the surface is often treated with a vegetable infusion, from locust bean pod or bark, which darkens and seals it.
The absence of the wheel is not a deficiency to be explained. Wheel-throwing and hand-building produce different things, and the large-diameter, thin-walled, round-bottomed forms of the Yoruba repertoire, including the great sunken dye pots, are not easily made on a wheel at all.
Gender. Pottery is overwhelmingly a women's craft, transmitted within lineages, in direct contrast to smithing, casting, bead embroidery, carving and narrow-strip weaving, all of which are men's.
Centres. Ìlọrin has the longest documented pottery heritage and the largest concentration of women potters in Kwara State and in Nigeria generally, with Dada Pottery at Ìlọrin a named contemporary workshop producing ìṣáasùn, ìkòkò agbo, orù, fìtílà and àmù . Ìṣẹ̀yìn is also significant. Ushafa near Abuja is frequently listed with these but is Gbagyi rather than Yoruba, and the distinction should be kept.
Ritual pottery. Òrìṣà worship is pot-dependent. The vessel holding Ọ̀ṣun's water and stones, the ìkòkò for Ṣàngó, the herbalist's ìkòkò agbo, and the vessels used for ìbejì are all fired pottery made by women. So is the ìkòkò aró in which the indigo dyers of Abẹ́òkúta worked, which means the women's dyeing industry rested on the women's pottery industry.
Norma Wolff published on Ìlọrin pottery in African Arts, and Sylvia Leith-Ross's Nigerian Pottery of 1970 catalogues the Jos Museum collection . Exact article titles and volumes for Wolff's Ìlọrin work were not verified for this file and are not asserted.
Calabash
The material. Igbá is the calabash or bottle gourd, Lagenaria siceraria. The tonal distinction from ìgbá, the locust bean tree, and from igba, two hundred, is not a curiosity; getting the tone wrong changes the word.
Techniques, usually combined on one vessel . Scraping, removing the outer skin in areas to expose lighter material beneath. Incising and carving, cutting the design into the skin with a knife or chisel. And pyro-engraving, burning the design into the surface with a hot iron.
Centres. Ọ̀yọ́ is the principal centre and is one of the most craft-oriented towns of the western states, noted specifically for calabash carving . Kwara and Ìlọrin also produce it. The Horniman Museum holds Stanfield photographs captioned as scraping the calabash at Ọ̀yọ́ and burning a design into a calabash at Lagos, which is direct visual documentation of both techniques in both places .
Uses. Bowls, spoons and ladles, water and palm wine containers, covered food vessels, cosmetic and medicine containers, prestige presentation vessels and bride gifts. The ṣẹ̀kẹ̀rẹ̀, the rattle netted with beads or cowries over a gourd, is a calabash and is one of the standard instruments of Yoruba ensembles. Ritual vessels for òrìṣà are calabashes as often as they are pots, and the arugbá, the calabash bearer, carries one.
The calabash also carries a cosmological argument. A closed calabash of two halves is the standard Yoruba model of the universe, the upper half the sky and the lower the earth, meeting at the horizon, and the phrase ìgbá ìwà, the calabash of existence or of character, uses the same image for a life. This is treated properly in the cosmology section; it is noted here because it explains why the material is used where it is.
Leather and the rest of the material world
Leatherworking is among the classic Yoruba trades, alongside smithing, weaving, glassmaking and carving . Ìlọrin and Ọ̀yọ́ are the centres, and Ìlọrin's tradition is strongly inflected by Hausa and Nupe technique and by Islamic patronage following the nineteenth-century Fulani conquest of the town. Products include cushions and pouffes, sandals and slippers, sword and knife sheaths, saddlery and horse trappings for the cavalry states, Qur'an satchels, amulet cases, fans and bags.
One trade fact is worth stating because it corrects a persistent misattribution. The dyed red and green goat and sheep skin sold in Europe as Morocco leather was substantially a Nigerian product, moving north across the Sahara and taking the name of its last port of call rather than its origin.
Court patronage is the organising fact. In the nineteenth century the rulers of the Yoruba kingdoms maintained elaborate palaces that were major patrons for artists in a wide range of media at once, including wood sculptors, leather workers, calabash carvers, drummers, bead artists, iron workers, brass casters, weavers, tailors and embroiderers . That is the correct frame for everything in this file and in the neighbouring ones. These were not independent village industries that happened to coexist. They were a linked patronage complex organised around courts, and the collapse of court revenue under colonial rule is the single largest cause of their decline.
Women also worked cotton spinning, basketry and dyeing . The remaining domestic material world, the mats, brooms, raffia and palm-frond baskets, wooden mortars and pestles and carved stools, is attested in general terms but has attracted little specialist scholarship, and nothing specific is asserted about it here.
History and evolution
Archaeological evidence places Yoruba metallurgy and craft specialization back into the early second millennium CE, rooted in the sophisticated brass casting and iron smelting traditions of ancient Ifẹ̀ . Under the expansion of the Ọ̀yọ́ Empire from the seventeenth through eighteenth centuries, craft production became deeply integrated into imperial administration and royal patronage, centralizing specialized guilds for blacksmithing, leatherworking, and calabash carving to support cavalry, palace ceremony, and regional trade .
The nineteenth-century Yoruba civil wars disrupted these traditional guild networks while simultaneously creating intense localized demand for military ironwork, weapons, and protective leather amulets. Following the collapse of Old Ọ̀yọ́ around 1835 and the spread of Fulani control over Ìlọrin, leatherworking techniques incorporated northern styles, while displaced artisans reconstituted workshops in emerging urban centers like Abẹ́òkúta and Ìbàdàn . During this same era, Christian missionary contact introduced new material imports and Western educational institutions that challenged the ritual authority of guilds, particularly by discouraging initiation into the Ògbóni society and devotion to Ògún .
Colonial rule in the late nineteenth and early twentieth centuries altered the economic foundation of indigenous crafts. The introduction of cheap European enamelware, iron tools, and factory-made textiles eroded the domestic market for hand-built pottery and smelted iron, while the decline of royal treasury funds dismantled court patronage systems . Nevertheless, craft guilds adapted by repurposing imported scrap metal and maintaining essential ritual items that European goods could not replace .
Following Nigerian independence in 1960, Yoruba craft traditions found new roles within national cultural heritage initiatives, modern academic art institutions, and the international tourist market . Today, while utilitarian metalware and domestic calabashes face competition from plastics and aluminum, traditional brass casting, ceremonial pottery, and Ògún shrine metalwork remain vital across southwestern Nigeria and throughout the transatlantic African diaspora, where practitioners in Cuba, Brazil, and North America continue to commission and consecrate these sacred forms , .
