  The status of lattice calculations in the light hadron sector is reviewed.
Special emphasis is given to recent lattice determinations of the mass of the
strange quark. The impact of non-perturbative renormalization and control over
lattice artefacts on the attainable precision is discussed in detail.
Furthermore the influence of dynamical quark effects is assessed.
