Adinkra are visual symbols that represent concepts or aphorisms. Adinkra are used extensively in fabrics and pottery among the Ashantis of Ashanti Kingdom and the baoules who historically migrated from Ghana. They are incorporated into walls and other architectural features. Fabric adinkra are often made by woodcut sign writing as well as screen printing. Adinkra symbols appear on some traditional Akan goldweights. The symbols are also carved on stools for domestic and ritual use. Tourism has led to new departures in the use of the symbols in such items as T-shirts and jewellery.
The symbols have a decorative function but also represent objects that encapsulate evocative messages that convey traditional wisdom, aspects of life or the environment. There are many different symbols with distinct meanings, often linked with proverbs. In the words of Kwame Anthony Appiah, they were one of the means for "supporting the transmission of a complex and nuanced body of practice and belief".
Ashanti oral tradition attributes the origin of adinkra to Gyaman in modern-day Ghana .The Englishman Thomas Edward Bowdich collected a piece of adinkra cloth in 1817, which demonstrates that adinkra art existed at least since this time. Bowdich obtained this cotton cloth in Kumasi, the capital of the Ashanti Empire. The patterns were printed using carved calabash stamps and a vegetable-based dye. The cloth features fifteen stamped symbols, including nsroma (stars), dono ntoasuo (double Dono drums), and diamonds. It is now in the British Museum.
The next oldest piece of adinkra textile was sent in 1825 from the Elmina Castle to the royal cabinet of curiosities in The Hague, in response to an assignment from Major F. Last, who was appointed temporary Commander of Dutch Gold Coast. He probably had the cloth commissioned for William I of the Netherlands, which would explain why the Coat of arms of the Netherlands is in the centre. The other motifs are typical of the older adinkras. It is now on display in the National Museum of Ethnology in Leiden.
