Akkian,Flavius Arrianus, the Grecio-Roman Biographer with Alexander, the Great , in His Book, it is also called as Indica like Megasthenes’s, describes the voyage of Alexander to India.

He chronicles  the customs and manners of the people of India.

“he Nysaeans are not an Indian race, but descended from the men who came into India with Dionysus–perhaps from those Greeks who were rendered unfit for service in the wars which Dionysus waged with the Indians. Perhaps also he settled with the Greeks those of the natives who were willing to join his colony. Dionysus named the city itself Nysa, and the land Nysaea, in honour of his nurse Nysa. The mountain near the city, at whose base Nysa was built, is called Meros (thigh) after the misfortune he experienced as soon as he was born. This is the story framed by the poets in regard to Dionysus, and let the writers of legends Grecian and foreign expound it. Among the Assacenians is Massaca, a large city, where also is the stronghold of the land of Assacia; and there is also another large city, Peucelaitis, not far from the Indus. These tribes have been settled west of the Indus as far as the Cophen….

 

Of the expedition of Dionysus, indeed, the city of Nysa is no mean monument, as also are the mountain Meros, the ivy which grows on this mountain, the Indians themselves also marching into battle to the sound of drums and cymbals, wearing speckled garments like the bacchanals of Dionysus. But of Heracles there are not many memorials. For the statement that Alexander forcibly subdued the rock of Aornus, because Heracles was not able to capture it, seems to me a piece of Macedonian boasting; just as they called the Parapamisus Caucasus, though it has no connection with it. And having observed a certain cave in the land of the Parapamisadians, they said that it was the famous cave of Prometheus, the son of the Titan, in which he was hung for the theft of the fire. And besides, in the land of the Sibians, an Indian race, because they saw the inhabitants clothed in skins, they said that the Sibians were those who had been left behind from the expedition of Heracles. The Sibians also carry cudgels, and the figure of a club was branded upon their oxen; this too they explained to be a commemoration of the club of Heracles. If anyone gives credit to these tales, this must have been another Heracles, neither the Theban, nor the Tyrian, nor the Egyptian; but some great king of a land situated in the interior not far from India.

 

He says that in ancient times the Indians were nomads, like that section of the Scythians who are not agriculturists, but wandering about on waggons, live at one time in one part of Scythia and at another time in another part, neither inhabiting cities nor consecrating temples to the gods. So the Indians had no cities or temples built for the gods. They clothed themselves in the skins of the wild beasts which they killed, and ate the inner bark of certain trees, which are called tala in the Indian language, and, as upon the tops of palm-trees, there grow upon them things like clews of wool. They also fed upon the flesh of the wild beasts which they caught, eating it raw, until Dionysus came into their country. But when Dionysus came and conquered them, he founded cities and made laws for them, and gave the Indians wine as he had given it to the Greeks. He also gave them seeds and taught them how to sow them in the earth; so that either Triptolemus did not come to this part when he was sent by Demeter to sow corn through the whole earth, or this Dionysus came to India before Triptolemus and gave to the inhabitants the seeds of cultivated crops. Dionysus first taught them to yoke oxen to the plough, and made most of them become husbandmen instead of being nomads, and armed them with martial weapons. He also taught them to worship the gods, and especiallyhttps://ramanisblog.in/2015/02/05/dionysus-greek-god-is-shiva-migrated-from-south-india/
