2. Hippalus was the Greek navigator and merchant, who is seemed to have first utilised the way to the Indian subcontinent directly from Red Sea area. Hippalus was the first to recognise the north south direction of Indian coast. Before him the Greek Geographers thought that the Indian coast stretched from West to east. Previous to this discovery the navigators used to sail close around the shores of Gulf and Makran coasts. But there is an alternate opinion that Arabs and Indians knew about South-West monsoon winds and made use of it in their voyage.
3. The anonymous author qualifies the land from Nora (Thikkodi) to Varkala( Paralia) by the name Damarica, meaning the land of Damar trees, the resin of which was used in incense and as disinfectant.
