Bhai Mardana Ji.(1459-1534)
Mardana Ji, a muslim minstral accompanied Guru Nanak Dev Ji on his Udasis (journeys). Together they travelled east to the far reaches of the Himilayas, south to the island of Sri Lanka, west to Mecca and Madina.
There is evidence that suggests that Guru Ji and Mardana Ji travelled to Rome also.
