Who is Sycorax? The first of all characters in William Shakespeare´s "The Tempest" to set foot on the island of the play. The problem is that Sycorax has no voice. She is barely mentioned by Prospero as a crooked, old, wicked witch who vilely locked Ariel, the spirit of the air, in a tree. But why would she lock Ariel in a tree? Here, we wouldn't believe Prospero so much.Mother of Caliban and imprisoner of Ariel, Sycorax remains offstage for the duration of The Tempest, dismissed by Prospero as an evil sorceress. In this collaboration between Lois Patiño and Matías Piñeiro, she becomes the central subject, as a director (played by Piñeiro regular Agustina Muñoz), with the help of local women from a village in the Azores, attempts to give a face and voice to this silenced character.
