| The work aims to point out an important aspect to be taken into account in the restoration of some singular façades, due to their singularity. Attention is focused on the sgraffiti that cover the walls of many palaces and houses of Segovia, a town located in the geographical centre of Spain, renown for its Roman aqueduct. Most of these sgraffiti are repetition patterns ¿regular mosaics¿ that can be studied from the point of view of geometry, due to the symmetries they have. The mathematical theory developed at the beginning of the 20th century considers the symmetries that leave the regular tiling unchanged and classifies them in 17 groups, called ¿wall-paper groups¿. In Spain there are two well-known examples of architectonic ornaments that contain the totality of these 17 groups: the arabesque in Alhambra of Granada and the Mudéjar art of Aragón. Symmetries of numerous sgraffiti in the town of Segovia and many villages surrounding it are analysed and 13 wall-paper groups have been identified. In this work, the distribution of different designs of sgraffito in wall-paper types has also been studied, and a non uniform distribution is the result. The old town of Segovia and its aqueduct was declared a World Heritage Site in 1985, and all of us should try to contribute to the future conservation of its singularity and its cultural legacy. Summing up, a new perspective is proposed to assess that cultural richness that has to be preserved. The restored façade should match the original façade in visual characteristics such as colour, texture, and what is new: the wall-paper symmetry group. | |
