Overview
Calabash carving is the decoration of dried gourds, practised widely across Nigeria and particularly associated with Oyo in the south-west, with Nupe work in Niger State, and with the Cross River area, where gourds were incised with nsibidi signs.
Origin and history
Gourd containers are among the oldest household objects in the region, and decorating them is long established wherever calabash grows. Regional styles are distinct: deep engraving and blackening in the south-west, fine pyro-engraved and pressure-engraved work in the middle belt, and sign-bearing gourds in the Cross River. Calabash remained a normal household material into the twentieth century, and although enamel, plastic and glass have displaced much of its everyday use, decorated gourds continue to be made for ceremony, gifts and sale.
Materials and techniques
A mature gourd is harvested, cleaned out, dried and cut to shape. Decoration is applied by incising the hard skin with a knife or blade, by burning lines and fields with a heated tool, by scraping away the surface layer to leave a pattern in relief, or by dyeing and staining. Cut lines may be rubbed with soot or dye so that the pattern reads dark against the pale skin. Larger vessels are made by joining a lid to a bowl, sometimes bound with leather or cord.
Cultural significance
Decorated calabashes serve as bowls, water and palm wine containers, spoons, rattles and drums, and they appear as marriage gifts and dowry items in several traditions, where the quality of decoration reflects on the giver. Because the object is both useful and displayed, the craft sits between household work and art, and the same motifs often recur on pottery, cloth and walls in the same area.
Notable examples
Pyro-engraved gourds
Bowls and bottles patterned with burnt line work, associated with middle belt and northern workshops.
Nsibidi-incised gourds
Cross River gourds carrying incised signs from the nsibidi repertoire.
Dowry calabashes
Large decorated vessels presented at marriage in several Nigerian traditions.
Connected history and culture
Signs incised on Cross River gourds belong to the nsibidi system, and the household use of decorated vessels overlaps with the pottery described in Gwari pottery.
