Q4. what is the similarity in the maps prepared by al idrisi and atlas nouveau of guillaume de isle
Answers
Answer:
Map 1 and Map 2 represent two different times. Map 1 was made in 1154 CE by al-Idrisi, an Arab geographer. This section is a detail of the Indian subcontinent from his larger map of the world. Map 2 was made by a French cartographer in 1720. Both maps are quite different from each other, even though they represent the same area. In Map 1 we find south India at the place where we would expect to find north India and Sri Lanka is the island at the top. The place names are in Arabic. Some familiar places like Kanauj in Uttar Pradesh have been spelled as Qanauj. In comparison to this Map 2 was made nearly 600 later after Map 1. By that time information about the subcontinent had changed a lot. This map appears to be more familiar to us. The coastal areas, particularly, are more detailed.
