For the Campinas edition of Mãe Preta in 2021, we invited the Casa de Cultura Fazenda Roseira and Comunidade Jongo Dito Ribeiro, Afro-Brazilian cultural groups in Campinas to create a new work for the exhibition. In a workshop using cyanotypes, members of these organizations used this old analogue photographic technique of exposing sensitized paper to sunlight to create a collection of images of sacred and medicinal plants cultivated in the former plantation house where the community meets regularly. This knowledge of plants for healing is handed down from generation to generation, and is now available for the public in Campinas to learn from in the exhibition set up at Instituto Pavão Cultural and also at the Fazenda Roseira itself.
