    2 3 4 5 Ministério da Cidadania e GetNet apresentam CURADORIA DE MARCELLO DANTAS FAROL SANTANDER 8 DE OUTUBRO DE 2019 A 5 DE JANEIRO DE 2020 Convidamos a todos para um passeio pela cultura de cinco continentes por meio da exposição ETNOS – Faces da Diversidade. A mostra apresenta 150 máscaras que expressam a multiplicidade da representação facial como instrumento de reconhecimento da identidade humana. Ao considerar que as máscaras nos dão a possibilidade de falar uma linguagem universal que não depende de idiomas, a exposição nos convida a refletir sobre a existência de uma comunicação não verbal que se estabelece, primordial- mente, por meio de símbolos. A sensação de mistério e encantamento propor- cionados pela evidência de uma linguagem capaz de prescindir do discurso, desconstrói convicções e concepções prévias e nos estimula à formulação de perguntas para as quais podem existir várias e distintas respostas. Um olhar atento e curioso para a multiplicidade de expressões que o ser humano se habilitou a produzir desde tempos ancestrais até a contempora- neidade foi o que nos conduziu para a construção desse projeto tão singular que agora trouxemos ao Farol Santander em São Paulo.
