Abstract: We combine ultradeep optical spectroscopy from the GMASS project ("Galaxy Mass Assembly ultradeep Spectroscopic Survey") with GOODS multi-band photometry and HST imaging to study a sample of passive galaxiesat 1.392. These galaxies have morphologies that are predominantly compact and spheroidal.However, their sizes (R_e 1, and absent if R_e<br />22 pages, 23 figures, Astronomy & Astrophysics, in press
