Transport jars from the Mycenaean citadel of Tiryns, a coastal centre in the Bronze Age, were analysed in a macroscopic and petrographic study. Over 400 vessels and vessel fragments, mostly Transport Stirrup Jars (TSJs) and Canaanite jars, were recorded; around a quarter of them were selected for analysis. The vessels derive from both the upper and lower citadel, with a few from the lower town. Their chronological span ranges from Late Helladic (LH) IIIB1 to LH IIIC Developed (ca 1300–1070 BC) but the bulk of the material dates to LH IIIB2 (ca 1200 BC), and comes from dumps derived from the final destruction of the palace. Several sources are suggested for the TSJs, some of which are inscribed with Linear B: Kythera, the eastern Aegean (perhaps Kos), Kontopigado-Alimos in Attica, Corinth and several other mainland sources, as yet unidentified. It is suggested that a large group of TSJs with shape and decoration derived from central Cretan types were produced in the vicinity of the Argive Plain. Two thirds of the TSJs, however, come from Crete. With the exception of one from the Vrokastro area of east Crete, these are evenly derived from the Chania plain and the western edge of the Mesara plain in central Crete, where the Minoan centres of Kommos, Phaistos and Ayia Triada are located. We discuss the implications of all this for our understanding of the economy and society of Crete after the destruction of the palace of Knossos, and for the relationship between Crete and the Mycenaean palatial centres in the Argolid
