Thinae (Greek: Θῖναι, or Σῖναι),^[1] or Thina (Θῖνα),^[2] was a capital city of the Sinae (modern China), who carried on there a large commerce in silk and woollen stuffs.^[3]

There appears to have been an ancient tradition that the city was surrounded with brazen walls; but Ptolemy remarks that these did not exist there, nor anything else worthy of remark. The ancient writers vary considerably as to its situation. According to the most probable accounts it was either Nanjing, or rather perhaps Thsin, Tin, or Tein, in the province of Shaanxi, where, according to the accounts of the Chinese themselves, the first kingdom of Sin, or China, was founded.^[3]
