Some recent results on light meson physics are reviewed. The new evidence of low mass scalar mesons together with an improved measurement of the phi radiative decays in scalar mesons, give new insight into the nature and the structure of the scalar spectrum. The evidence of new states with a mass close to twice the proton mass, and a new analysis of the gluonium content of the eta' are discussed.
