which he incidentally describes as a civilization similar to that of Bactria: Recent excavations at the burial site of China's first Emperor Qin Shi Huang, dating back to the 3rd century BCE, also suggest Greek influence in the artworks found there, including in the manufacture of the famous Terracotta army. It is also suggested that Greek artists may have come to China at that time to train local artisans in making sculptures. Indian Ocean trade Maritime relations across the Indian Ocean started in the 3rd century BC, and further developed during the time of the Indo-Greeks together with their territorial expansion along the western coast of India. The first contacts started when the Ptolemies constructed the Red Sea ports of Myos Hormos and Berenike, with destination the Indus delta, the Kathiawar peninsula or Muziris. Around 130 BC, Eudoxus of Cyzicus is reported (Strabo, Geog. II.3.4) to have made a successful voyage to India and returned with a cargo of perfumes and gemstones. By the time Indo-Greek rule was ending, up to 120 ships were setting sail every year from Myos Hormos to India (Strabo Geog. II.5.12). Armed forces The coins of the Indo-Greeks provide rich clues on their uniforms and weapons. Typical Hellenistic uniforms are depicted, with helmets being either round in the Greco-Bactrian style, or the flat kausia of the Macedonians (coins of Apollodotus I). Military technology Their weapons were spears, swords, longbow (on the coins of Agathokleia) and arrows. Around 130 BC, the Central Asian recurve bow of the steppes with its gorytos box started to appear for the first time on the coins of Zoilos I, suggesting strong interactions (and apparently an alliance) with nomadic peoples, either the Yuezhi or the Scythians. The recurve bow becomes a standard feature of Indo-Greek horsemen by 90 BC, as seen on some of the coins of Hermaeus. Generally, Indo-Greek kings are often represented riding horses, as early as the reign of Antimachus II around 160 BC. The equestrian tradition probably goes back to the Greco-Bactrians, who are said by Polybius to have faced a Seleucid invasion in 210 BC with 10,000 horsemen. Although war elephants are never represented on coins, a harness plate (phalera) dated to the 3–2nd century BC, today in the Hermitage Museum, depicts a helmetted Greek combatant on an Indian war elephant. The Milinda Panha, in the questions of Nagasena to king Menander, provides a rare glimpse
