The article explores the historical Mexican tradition of 'La muerte niña,' where post-mortem photographs of deceased infants and children were created during the late 19th and early 20th centuries. This practice, rooted in colonial art traditions, served as a way for families to preserve memories amid high infant mortality rates. Unlike modern perspectives that may view such images with unease, Mexican communities embraced these children as 'angelitos' (little angels), believing they ascended to heaven without sin. The photographs were highly stylized, often featuring children dressed in white gowns or as saints, adorned with floral crowns and religious symbols like crosses or lilies. Staging emphasized spiritual transformation rather than mortality, with infants depicted in beds surrounded by flowers or held by family members. Photographers like Romualdo García and Juan de Dios Machain documented these rituals, creating socio-historical archives. By the mid-20th century, shifts in Catholic practices and improved healthcare led to the decline of this genre. The article highlights how these images reflect cultural beliefs about purity, divine intercession, and familial grief.
