In 1981 W.L. Edge discovered and studied a pencil $mathcal{C}$ of highly symmetric genus $6$ projective curves with remarkable properties. Edges work was based on an 1895 paper of A. Wiman. Both papers were written in the satisfying style of 19th century algebraic geometry. In this paper and its sequel [FL], we consider $mathcal{C}$ from a more modern, conceptual perspective, whereby explicit equations are reincarnated as geometric objects.
