La recepción de Isaías 43.20 en Adversus Marcionem de Tertuliano: las sirenas como un tipo de los “gentiles” y como un caso de hibridismo cultural

Tertullian in his work Adversus Marcionem quotes Isaiah 43.20, which is peculiar because it documents a reference to sirens. This article aims to review Tertullian’s interpretation of Isaiah’s text to determine possible sources. A historical-philological methodology is followed where initially the text’s meaning is defined through the author’s context and then approaches to the cultural horizon of the Patristics of the first centuries. The evidence reveals a close relationship with Clement of Alexandria; consequently, the existence of a common cultural background between the two writers can be inferred. Thus, Tertullian ends up participating in the same process of cultural hybridization as other authors of his time.
