Clothes and textiles make up a very relevant part or religious cultural heritage. This paper presents a selection of liturgical textiles from the 18th and 19th centuries. They were created by Garín, a Spanish factory still active today. The designs and weaving techniques employed in them have provided the starting point for a research project, SILKNOW, in operation between 2018 and 2021. It aims to apply cutting-edge computing technologies to textile heritage, including the religious and liturgical, and thus establish new historical and artistic connections. The research leading to these results is carried out within the SILKNOW project (¿Silk heritage in the Knowledge Society: from punched cards to big data, deep learning and visual/tangible simulations"), which has received funding from the European Union"s Horizon2020 research and innovation program under grant agreement No. 769504.
