Intense westward physical exchange at that time along the Silk Road is confirmed by the Roman craze for silk from the 1st century BC to the point that the Senate issued, in vain, several edicts to prohibit the wearing of silk, on economic and moral grounds. This is attested by at least three authors: Strabo (64/63 BC – ), Seneca the Younger ( – AD 65), and Pliny the Elder (AD 23–79). The aforementioned Strabo and Plutarch (–125) also wrote about Indo-Greek Buddhist king Menander, confirming that information about the Indo-Greek Buddhists was circulating throughout the Hellenistic world.
