  We operated a PbMoO$_4$ scintillating cryogenic detector of 570 g, produced
with archaeological lead. This compound features excellent low temperature
characteristics in terms of light yield, 12 keV/MeV for $\beta/\gamma$
interactions, and FWHM energy resolution, 11.7 keV at 2.6 MeV. Furthermore, the
detector allows for an effective particle identification by means of pulse
shape analysis on the heat read-out channel. The implementation of innovative
techniques and procedures for the purification of raw materials used for the
crystal growth, and the highly-pure archaeological Pb, allowed the production
of large volume high quality crystal. The overall characteristics of the
detector operated at cryogenic temperatures makes PbMoO$_4$ an excellent
compound for neutrino physics applications, especially neutrinoless double-beta
studies.
