The minuscule homogeneous varieties include the projective spaces, the Grassmannians, the spinor varieties, quadrics, the Cayley plane and Freudenthal's variety.
I prove that a vector bundle on a minuscule homogeneous variety splits into a direct sum of line bundles if and only if its restriction to the union of two-dimensional Schubert subvarieties splits. A case-by-case analysis is done.
