A Final Palatial lapis lacedaemonius seal, here called the Sissi Genius Lentoid, was recovered during the 2018 excavation of the Court-Centered Building at Sissi, East Crete. The seal instantly drew attention because of its rare material and unique iconography that shows a Minoan genius flanked by the foreparts of two agrimia. An examination of the object within the context of Late Minoan II–III hard stone glyptic, particularly the lapis lacedaemonius seals, reveals ideological and sociopolitical links between Sissi and other Cretan sites, including neighboring Malia. The lentoid belongs to a group of seals that clearly formed prestige items used by sociopolitical elites who were exercising control over the surrounding land, possibly as delegates of the Knossos palace.
