In 1988, Lydia Cabrera (1899-1991) published La lengua sagrada de los igos, an Abaku phrasebook that is to this day the largest work available on any African diaspora community in the Americas. In the early 1800s in Cuba, enslaved Africans from the Cross River region of southeastern Nigeria and southwestern Cameroon created Abaku societies for protection and mutual aid. Abaku rites reenact mythic legends of the institution's history in Africa, using dance, chants, drumming, symbolic writing, herbs, domestic animals, and masked performers to represent African ancestors. Criminalized and scorned in the colonial era, Abaku members were at the same time contributing to the creation of a unique Cuban culture, including rumba music, now considered a national treasure. Translated for the first time into English, Cabrera's lexicon documents phrases vital to the creation of a specific African-derived identity in Cuba and presents the first "insider's" view of this African heritage. This text presents thoroughly researched commentaries that link hundreds of entries to the context of mythic rites, skilled ritual performance, and the influence of Abaku in Cuban society and popular music. Generously illustrated with photographs and drawings, the volume includes a new introduction to Cabrera's writing as well as appendices that situate this important work in Cuba's history. With the help of living Abaku specialists in Cuba and the US, Ivor L. Miller and P. Gonzlez Gmes-Csseres have translated Cabrera's Spanish into English for the first time while keeping her meanings and cultivated style intact, opening this seminal work to new audiences and propelling its legacy in African diaspora studies.
