We propose simultaneous neutron measurements on the INES beamline aiming to characterize the composition in terms of phases and elements of a large set of ancient orichalcum ingots. They were found near remains of a ship and earthenware dated around the end of the VI century BC, and coming from the eastern Mediterranean and the Aegean sea. The analytical investigations will provide information essential to determine the metal composition in terms of phase and elements. We have in program to investigate the same samples with different techniques to obtain complementary information using GEM and IMAT.
