Combining the recent lattice calculation of a_0(1450) and σ(600) mesons with the overlap fermion in the chiral regime with the pion mass less than 300 MeV, the quenched lattice calculation of the scalar glueball, and the phenomenological study of the mixing of isoscalar scalar mesons f_0(1710), f_0(1500), f_0(1370) through their decays, a simple pattern for the light scalar mesons begins to emerge. Below 1 GeV, the scalar mesons form a nonet of tetraquark mesoniums. Above 1 GeV, the nonent qq mesons are made of an octet with largely unbroken SU(3) symmetry and a fairly good singlet which is f_0(1370). f_0(1710) is identified as an almost pure scalar glueball with a〜10% mixture of qq.
