Facilitated by the volumes of the Corpus der minoischen und mykenischen Siegel (Berlin 1960–2009), scholars studying Minoan and Mycenaean seal stones and sealings of the Aegean Bronze Age (ca. 2300–1300 BCE) have worked in two major areas: chronology and function. Chronology is now well understood through a process of creating a stylistic typology for seals that can be fixed in time through seals from stratigraphic excavations. Understanding the function of seals relies on a detailed typology of sealings and their role in administration as witnessed by documents written in the three major Aegean scripts, Cretan Pictographic and Linear A and B.
