We present results on the static three- and four-quark potentials in SU(3)and SU(4) respectively within quenched lattice QCD. We use an analyticmulti-hit procedure for the time links and a variational approach to determinethe ground state. The three- and four-quark potentials extracted are consistentwith a sum of two-body potentials, possibly with a weak many-body component.The results give support to the $\Delta$ ansatz for the baryonic area law.Comment: improved formatting of figures, typo correcte
