There is an old art called diamanga in Madagascar (apparently there are old engravings that represent it, but I do not know the dates), this style has fallen into disuse and today it goes through a resurrection. The diamanga seems to have much similarity with the silat and would descend from it, slaves from Madagascar were imported into Brazil in the 17th century and brought the diamanga where it was mixed with traditions of the African continent, such as n'golo and bassula, ritualistic tribes many different. The history of the Malagasy in Brazil is obscure, since they were few among many people coming from the African continent. Today we notice some similarities between capoeira and silat, this theory would explain this. I am a layperson and have discovered these things on the internet and would like people with understanding to help me understand silat and diamanga.
