Un mural románico en la iglesia de san Millán de Segovia. Transmigración de modelos textuales y de modelos visuales en el arte medieval

In 1974 a set of Medieval wall paintings was brought to light in the Romanesque church of San Millán of Segovia. Three different ensembles are to be discerned. They all are located on the very same wall, on the north end of the north transept. In this article attention is paid to the oldest one, placed on the top of the wall, inscribed by a round arch which makes it to resemble a tympanum. This mural, soon recognized as an hagiographical one probably dealing with St Millán, the patron-saint of the church, had been never analysed in depth. It is now discussed in the context of Romanesque painting in Segovia. Its arrangement and function are considered and, above all, interest is focused on how its iconographic display was created on the basis of textual and visual sources and on how it persisted in later works, mainly the tympanum of the south door of the church.
