Variational calculations are presented of the masses of the lightest scalar and tensor glueballs in quarkless SU(3) gauge theory at lattice coupling {β}=6.0 on a large lattice. The scalar-glueball mass is consistent with previous nonvariational calculations on lattices of similar sizes. The tensor-glueball mass is greater than the scalar-glueball mass.
