  We derive the galaxy luminosity functions in V, R, I, and K bands of the
cluster EIS 0048 at z~0.64 from data taken at the ESO Very Large Telescope. The
data span the restframe wavelength range from UV, which is sensitive to even
low rates of star formation, to the NIR, which maps the bulk of the stellar
mass. By comparing our data and previous results with pure luminosity evolution
models, we conclude that bright (M<= M^*+1) cluster galaxies are already
assembled at z~1 and that star formation is almost completed at z~1.5.
