A more recent mural is on the walls of the former Calamai factory commissioned by the Metastasio Theatre. The work was created by Dem, a famous Lombard street artist. The mural is clearly visible from the cycle path that runs along Viale Galilei. It is inspired by mythological and fantastic figures, which mix human beings, animals and plants and represents the complexity of the city of Prato: the couple on the left indicates the elements that follow and tell about Prato and its profound changes, starting from history (the Etruscan under the full moon), passing through the Chinese Woman, which refers to the great Chinese community of Prato, to the Tree Man which indicates the attachment to nature and the South African Afro Dancer, symbol of the respective communities, up to get to the last figure, the Unimaginable, a desirable future where the various elements come together to give life to something new. This last figure in fact recalls, in form and in the motifs, all those preceding it and holding a sign with the word "MET" (which stands for Metastasio).
