Evans dates the Lapidary's Workshop, located in the south-west basements of the Palace at Knossos, to his Re-occupation Period (LM IIIB), thus making it and its contents one of three stone jewellery workshops known for the period LM/LH III B, and implying that after LM IIIA 1(/2) part of the Palace at least remained an artistic and administrative centre (if the making of sealstones here implies their concomitant use as impressing agents for sealing sets of documents, tombs, etc.). Other scholars, however, such as Boardman, date the Workshop prior to LM IIIA 1(/2), on the basis of the styles of the motifs carried on the clay nodules and of the unfinished sealstones found in the Workshop.
