We present a projective framework for the construction of Integration byParts (IBP) identities and differential equations for Feynman integrals,working in Feynman-parameter space. This framework originates with very earlyresults which emerged long before modern techniques for loop calculations weredeveloped. Adapting and generalising these results to the modern language, weuse simple tools of projective geometry to generate sets of IBP identities anddifferential equations in parameter space, with a technique applicable to anyloop order. We test the viability of the method on simple diagrams at one andtwo loops, providing a unified viewpoint on several existing results.
