The Vai syllabary was invented in about 1820 in Liberia by Momolu Duwalu Bukele, who was inspired by a dream to create a writing system for the Vai language. In 1854 a German philologist, S. W. Koelle, met Duwalu Bukele while researching the Vai language and was told that in Bukele's dream a tall, venerable-looking white man in a long coat appeared and said "I am sent to you by other white men ... I bring you a book." Bukele was then shown many signs, but couldn't remeber them when he woke up, so he made new signs with some friends.
Another theory about the origins of the Vai syllabary is that it developed from ancient pictographs, and that Bukele possibly phoneticized those symbols.
The syllabary proved popular with the Vai and by the end of the 19th century most of them were using it. In 1962 the Standardization Committee at the University of Liberia standardized the syllabary. A Vai version of the New Testament in the Vai script appeared in 2003.
