  The ground state and excited spectra of baryons containing three identical
heavy quarks, $b$ or $c$, have been recently calculated in nonperturbative
lattice QCD. The energy of positive and negative parity excitations has been
determined with high precision. Lattice results constitute a unique opportunity
to learn about the quark-confinement mechanism as well as elucidating our
knowledge about the nature of the strong force. We analyze the nonperturbative
lattice QCD results by means of heavy-quark static potentials derived using
SU(3) lattice QCD. We make use of different numerical techniques for the
three-body problem.
