Following the discovery of two new scalar mesons {ital f}{sub 0}(1370) and {ital f}{sub 0}(1500) at the Low Energy Antiproton Ring at CERN, we argue that the observed properties of this pair are incompatible with them both being {ital QQ{vert_bar}} mesons. We show instead that {ital f}{sub 0}(1500) is compatible with the ground state glueball expected around 1500 MeV mixed with the nearby states of the 0{sup +}{sup +}{ital Q}{ital Q}{vert_bar} nonet. Tests of this hypothesis include the prediction of a further scalar state {ital f}{sub 0}{sup {prime}}(1500{endash}1800) which couples strongly to {ital KK{vert_bar}}, {eta}{eta}, and {eta}{eta}{prime}. Signatures for a possible tensor glueball at {approximately}2 GeV are also considered. {copyright} {ital 1995 The American Physical Society.}
