We employ the recent discovery of functoriality for persistent homology to recast the Persistent Homology Transform of a geometric complex as a cosheaf of combinatorial persistence diagrams. Detailed examples are provided. We hope the recasting of the PH transform as a cellular cosheaf will allow for the adoption of existing methods from category theory and (co)sheaf theory to the study of shapes.
