  Properties of finite nuclei are investigated based on relativistic Hartree
equations which have been derived from a relativistic quark model of the
structure of bound nucleons. Nucleons are assumed to interact through the
(self-consistent) exchange of scalar ($\sigma$) and vector ($\omega$ and
$\rho$) mesons at the quark level. The coupling constants and the mass of the
$\sigma$-meson are determined from the properties of symmetric nuclear matter
and the rms charge radius in $^{40}$Ca. Calculated properties of static,
closed-shell nuclei, as well as symmetric nuclear matter are compared with
experimental data and with the results of Quantum Hadrodynamics (QHD).
