numerous and the most widespread of all the Indo-Greek kings. Menander is also remembered in Buddhist literature, where he is called Milinda, and is described in the Milinda Panha as a convert to Buddhism: he became an arhat whose relics were enshrined in a manner reminiscent of the Buddha. He also introduced a new coin type, with Athena Alkidemos ("Protector of the people") on the reverse, which was adopted by most of his successors in the East. Fall of Bactria and death of Menander From the mid-2nd century BC, the Scythians, in turn being pushed forward by the Yuezhi who were completing a long migration from the border of China, started to invade Bactria from the north. Around 130 BC the last Greco-Bactrian king Heliocles was probably killed during the invasion and the Greco-Bactrian kingdom proper ceased to exist. The Parthians also probably played a role in the downfall of the Bactrian kingdom. Immediately after the fall of Bactria, the bronze coins of Indo-Greek king Zoilos I (130–120 BC), successor of Menander in the western part of the Indian territories, combined the club of Herakles with a Scythian-type bowcase and short recurve bow inside a victory wreath, illustrating interaction with horse-mounted people originating from the steppes, possibly either the Scythians (future Indo-Scythians), or the Yuezhi (future Kushans) who had invaded Greco-Bactria. This bow can be contrasted to the traditional Hellenistic long bow depicted on the coins of the eastern Indo-Greek queen Agathokleia. It is now known that 50 years later, the Indo-Scythian Maues was in alliance with the Indo-Greek kings in Taxila, and one of those kings, Artemidoros seems to claim on his coins that he is the son of Maues, although this is now disputed. Preservation of the Indo-Greek realm The extent of Indo-Greek rule is still uncertain and disputed. Probable members of the dynasty of Menander include the ruling queen Agathokleia, her son Strato I, and Nicias, though it is uncertain whether they ruled directly after Menander. Other kings emerged, usually in the western part of the Indo-Greek realm, such as Zoilos I, Lysias, Antialcidas and Philoxenos. These rulers may have been relatives of either the Eucratid or the Euthydemid dynasties. The names of later kings were often new (members of Hellenistic dynasties usually inherited family names) but old reverses and titles were frequently repeated by the later rulers.
