It used to be that interest in the ages of the globular clusters was primarily motivated by cosmological considerations. In recent years, remarkable progress in the quality and quantity of observations and advances in the understanding of stellar atmospheres and in the construction of theoretical isochrones make possible the use of globular clusters as probes of galactic evolution. A new picture, still tentative at this point, is emerging of the formation and chemical enrichment of the halo, in its nucleus and in its outer reaches through observations of globular clusters, dwarf spheroidal galaxies and the Magellanic Clouds.
