In the early days of modern archaeology the first to propose an identification of the shapes of vases was Panofka,[500] whose fanciful and uncritical lucubrations were shortly afterwards combated by Letronne[501] and Gerhard,[502] the latter of whom introduced a more scientific method of criticism and classification, though his results cannot be considered as final. Other writers were Müller,[503] Thiersch,[504] Ussing,[505] Krause,[506] and Jahn,[507] of whom Ussing followed practically on Gerhard’s lines but with more success; Krause, though exhaustive, is on the whole uncritical; and Jahn has treated the subject with his wonted conciseness and sobriety. Of late years little attention has been paid to it, principally, no doubt, for the reason that so many conventional names have been generally accepted for the ordinary shapes by archaeologists, who have recognised the fact that it will never be possible to treat the subject with scientific accuracy.[508] The classification of the shapes of vases has usually been undertaken on the lines of distinguishing their main uses, such as (1) those in which food or liquids were preserved; (2) those in which liquids were mixed or cooked; (3) those by means of which liquids were poured out or food distributed; (4) drinking-cups; (5) other vases for the use of the table or toilet. Thus we have the pithos and amphora for storing wine, the krater for mixing it, the psykter for cooling it, the kyathos for ladling it out, and the oinochoë or prochoos for pouring it out; the hydria was used for fetching water from the well. Of smaller vases, the names for drinking-cups are innumerable, but the phiale, for instance, was employed chiefly for pouring libations; while dishes and plates are represented by the lekane, tryblion, pinax, and so on. The pyxis was used by women at their toilet, and the lekythos, alabastron, and askos for holding oil and unguents. There is an interesting passage in Athenaeus (iv. 142 D)[509] which gives a list of the vases required for use at a banquet: “And on the tripod was placed a bronze wine-cooler (ψυκτήρ) and a κάδος (bucket) and a silver σκαφίον holding two kotylae (one pint), and a ladle (κύαθος); and the wine-jug (ἐπίχυσις) was of bronze, but nobody was offered drink unless he asked for it; and one ladleful was given out before the meal.” * * * * * For the purposes of this work it is hoped that the usual method of classification indicated above will be found sufficient, supplemented by the descriptions of Athenaeus and other writers, where any details can be obtained; but it is obvious that a really critical treatment of the subject should be chronological, with endeavours to trace the first appearance and development of each type. In the present state of our knowledge, however, it would seem impossible to do so with success.
