Total and differential cross sections for photoproduction of eta mesons from C-12, Ca-40, Nb-93 and Pb-nat have been obtained up to 790 MeV incident photon energy at the Mainz Microtron (MAMI) with the TAPS spectrometer. The absorption cross section sigma(eta N)(abs) = (30 +/- 2.5 +/- 6) mb of eta mesons in nuclear matter and the absorption length lambda(eta) = (2.0 +/- 0.2 +/- 0.4) fm are extracted. No significant depletion of the S(1)1(1535) strength in the eta photoproduction on nuclei is observed.
