                            Description
                                    In recent years accurate photometric and spectroscopic observations have
 provided sound evidence that Galactic Globular Clusters can not be longer
 considered the prototype of Simple Stellar Populations. In this talk we
 present the most recent updates concerning the empirical evidence and
 discuss the theoretical framework required for interpreting observations.
 Current shortcomings in the interpretation of how the multiple stellar
 populations formed in a given cluster are also discussed.
