  We have compared the results from a model for the chemical evolution of an
elliptical galaxy with initial luminous mass of 2x10^10 M_sun and effective
radius of 2 kpc with the recent abundance determinations for the Lyman-break
galaxy MS 1512-cB58 at a redshift z=2.7276. After correcting the iron abundance
determination for the presence of dust we concluded that the observed [Si/Fe],
[Mg/Fe], [N/Fe] are consistent with our model when a galactic age between 20
and 35 Myr is assumed. Moreover, the [N/O] ratio also suggests the same age.
This age is in very good agreement with other independent studies based on the
analysis of the spectral energy distribution suggesting that this object is
younger than 35 Myr. Therefore, we suggest that MS 1512-cB58 is a truly young
normal elliptical galaxy experiencing its main episode of star formation and
galactic wind.
