  The moduli stack M_X(E_8) of principal E_8-bundles over a smooth projective
curve X carries a natural divisor Delta. We study the pull-back of the divisor
Delta to the moduli stack M_X(P), where P is a semi-simple and simply connected
group such that its Lie algebra Lie(P) is a maximal conformal subalgebra of
Lie(E_8). We show that the divisor Delta induces "Strange Duality"-type
isomorphisms between the Verlinde spaces at level one of the following pairs of
groups (SL(5), SL(5)), (Spin(8), Spin(8)), (SL(3), E_6) and (SL(2), E_7).
