Maria Lai (1919–2013) is one of the most significant figures in 20th-century Italian art, known for her poetic and symbolic use of textile materials. Her artistic practice is deeply rooted in the traditions of her native land, Sardinia, which she drew upon not only for materials such as thread, fabric, looms, and bread, but also for themes tied to collective memory, myth, ritual, and folk knowledge. Through thread and the act of sewing, Maria Lai elevated traditionally feminine domestic practices into an artistic language, transforming them into tools of emancipation, memory, and resistance, and restoring dignity to a form of knowledge often marginalized. Her work, deeply imbued with a sense of the sacred and inspired by folk legends, engages in a profound reflection on themes such as identity, belonging, memory, and connection. In her piece Fili di pietra, the interwoven threads become a metaphor for bonds, relationships, and shared memories, in perfect harmony with her famous motto: “To be is to weave.” Here, thread takes on a universal symbolic value, evolving from a traditional feminine tool into a vehicle for storytelling, connection, and meaning-making.
