This table comes from A. K. Akishev's Art and Mythology of the Sakas (Alma-Ata, 1984), Table X. It arranges the dynastic signs found on Kushan coins by king, and it remains the most reproduced single image of the Kushan tamga system. It is worth reading carefully, both for what it captures and for where the scholarship has moved past it.
A tamga is a property mark of the kind used by nomadic clans across the Eurasian steppe from the Scythian period onward. It was branded on horses, impressed into bricks and pottery, cut into rock, and, once nomadic dynasties began minting, placed on coins as a mark of the issuing house. The Kushans inherited the practice from their Yuezhi origins in the Gansu corridor and the Ili valley, and they carried it into Bactria and then across the Hindu Kush into Gandhara and the Punjab. Sergey Yatsenko, whose comparative work on Sarmatian, Chorasmian and Kushan signs is the standard reference, has shown that the Kushan version follows a two-part grammar. The upper element is a pronged fork shared by the whole dynasty, a clan sign. The lower element is a personal device that changes with each ruler. Reading a Kushan tamga therefore means reading two things at once: membership of the ruling clan, and the identity of the king.
The table shows that grammar developing. In the first row the fork has three prongs and sits on a ring or a hooked stem. From the second row onward the fork has four prongs, and the variation moves entirely into the base. Wima Kadphises places the fork over splayed legs that resemble pincers. Kanishka keeps the pincer legs and adds curled or flowering terminals. Huvishka's signs, the largest group in the table, set the fork over stick-figure legs in a dozen variants, one leg straight and one bent, or crossed, or with feet; these variants track mints and production phases rather than any change of ruler, since the main Bactrian mint and the subsidiary mints in Gandhara and Kashmir each cut their own dies. Vasudeva I retains the stick legs and adds a crossbar. Vasudeva II reduces the base to a single lozenge-shaped pendant. The fork never changes; the base always does. That is precisely what a clan-plus-individual system predicts.
The table's weakness is its king list. Akishev published in 1984, nine years before the discovery of the Rabatak inscription in 1993, which settled the early Kushan succession. Rabatak confirmed that a king named Wima Takto reigned between Kujula Kadphises and Wima Kadphises, and that the large anonymous coinage bearing only the titles Soter Megas, "great saviour," belongs to him. Akishev's two "Kadfiz" rows therefore compress three reigns into two. The ring-based three-pronged signs in his first row are the Soter Megas type, and so most likely Wima Takto's rather than Kujula's. Kujula's own earliest tamga, as Yatsenko notes, is close to that of the Indo-Parthian king Gondophares whose territory he took over, which is what one expects of a ruler legitimising himself in a region with an existing coinage. The Kushan tamga as a distinct dynastic sign crystallises under Wima Takto and Wima Kadphises, not under the founder.
The last row is a further caution. "Bakarna" corresponds to no name in the thirteen-king sequence now accepted (Kujula, Wima Takto, Wima Kadphises, Kanishka I, Huvishka, Vasudeva I, Kanishka II, Vasishka, Kanishka III, Vasudeva II, Mahi, Shaka, Kipunadha). It is probably a misread legend, or an issue of one of the later kings whose names were only recovered from the vertical Brahmi inscriptions on their gold after Göbl's work of the same year. The single trident-headed sign in the Kanishka row also looks less like a royal tamga than the trident of the god Wesho on the reverse, and should be checked against the source coin before it is used.
What makes the table useful today, despite these problems, is practical. Kushan copper circulated for centuries and is often found worn beyond legibility. The tamga survives wear better than the legend, because it is cut deep and sits in the field. For a site like Sanghol in the Punjab, where the excavators report coins of Soter Megas, Wima Kadphises and Kanishka around the stupa, or Ropar, where a hoard of some 660 coppers is described only as "Kushan and tribal Kushan," the tamga is frequently the only way to assign a coin to a reign. The modern catalogue to use for that is Jongeward and Cribb's Kushan, Kushano-Sasanian, and Kidarite Coins (American Numismatic Society, 2015), which supersedes both Göbl and Akishev on attribution. The Akishev table is best treated as a visual index to be read against it.
One final point, because it comes up whenever tamgas are discussed. A shared tamga indicates a shared political claim, membership of a clan or a dynastic house. It does not indicate shared biological descent. The Kushanshah governors who ruled Bactria for the Sasanians after about 230 CE went on reproducing Vasudeva I's tamga for decades, and Yatsenko has traced identical signs across groups in Sarmatia and Chorasmia that no one supposes were kin. Tamgas are evidence for how power was signalled, and they are good evidence for that. They are not a substitute for genetics, and the two lines of argument should be kept apart.
