Artist Jack Robbins created a series of porcelain enamel markers for San Pedro Springs Park, working for three years with an array of groups to ensure historical and cultural accuracy. Robbins’ images are visually and conceptually complex. For example, his “Beginnings” panel is derived from a drawing of the wall of the human heart as seen through an electron microscope. The artworks also incorporate the park’s history, including descendants of the Coahuitecan tribe who inhabited the area before Spanish explorers arrived in 1709.
