The Canary Islands rose from the sea around 35 million years ago. But when did humanity know about their existence? We'll never know, but at least we know a couple of facts:
- the first mention ever founded from the Canary Islands go back to the 8th century B.C. The greek poet Homer speaks in his texts about islands that would be the paradise on earth. This islands would be beyond the Hercules columns (Gibraltar Strait between Spain and Marocco). So at least by that time the Greeks knew the islands were here.
- Man made materials from around 1.000 BC have been found on the island but no sign of a permanent settlement. Thus, it is believed that the islands were known by sailing empires such as the Fenicians and Greeks. But without permanent settlements.
- It is around the 1st century BC where the Guanches settled for sure in the Canary Islands and started the part of Gran Canaria history we know more about. From this moment on there are plenty of discoveries that proof that the islands were populated at that time.
- Juba II, the king of Mauritania and part of the Roman Empire. sent an expedition a couple of decades after Christ's birth to the already populated Canary Islands. The report of his expedition is the oldest and one of the main written documents in Gran Canara history.
Thus, we know for sure that the islands were populated around the 1st century B.C. and that their existence was already known at least in the 8th century B.C. Anything prior to this, is blurry. But the biggest question is: whenever they arrived, how did the Guanches get here?
