In the Rhodian amphorae two stamps are in use, a principal and an accessory one (Fig. 23._a_).[525] The former has a device of the head of Helios, the Sun-God, or the emblematic rose, both of which types occur on the coins; it is accompanied by an inscription, in the form ἐπὶ τοῦ δεῖνος, sometimes explicitly described as ἱερέως, _i.e._ in the year of the eponymous priest of the Sun. This is followed by the name of a Rhodian month. The accessory stamp contains the name of a person, usually in the genitive. The months belong to the Doric calendar, and are as follows: Thesmophorios, Theudaisios, Pedageitnyos, Diosthyos, Badromios, Sminthios, Artamitios, Agrianios, Hyakinthios, Panamos, Dalios, Karneios, and the second Panamos, an intercalary month.[526] The object of the stamps is involved in obscurity, but they were probably intended to certify that the amphora (which was also a measure) held the proper quantity. It is clear that they could not have been intended to attest the age of the wine, as the vessel might be used for any sort, and the stamps bear the name of every month in the year. [Illustration: From _Dumont_. FIG. 23. AMPHORA-STAMPS FROM RHODES. ] Other handles of Rhodian amphorae, stamped with an oblong cartouche or label, may be divided into two classes: (1) Those inscribed with the name of a magistrate and an emblem. The latter resembled the “adjuncts” found on the coins of some Greek cities, but it is uncertain whether they were selected on any fixed principle, or merely adopted from caprice. They may perhaps allude to the deity whom the magistrate particularly honoured as the patron god of his tribe or village. The same symbol was, however, often used by many individuals, and on the whole the number known is not large. (2) Those bearing the name of a magistrate, accompanied by that of a month of the Doric calendar, but without any emblem (Fig. 23._b_). Many handles of amphorae from Knidos have been found on different sites. Their clay is coarser than the Rhodian, its colour darker and duller, and the amphorae differ also somewhat in form, nor are they of so early a date, being mostly as late as the Roman Empire. The stamps on the Cnidian amphorae, like those of Rhodes, are inscribed with the name of the eponymous magistrate, and also with that of the wine-grower or exporter of the produce, which is always marked as Cnidian. The stamps show a great variety in the matter of emblems. Remains of Cnidian amphorae have been found in Sicily, at Athens, Alexandria, and Olbia. The palaeography of the inscriptions covers a period of two centuries, from Augustus to Marcus Aurelius, or even later.
