Describe bedes attitude towards Caesars attempted invasions of Britain?

Whatever their reasons for exploring, Europeans wouldn’t have gotten very far without advances in technology. Sailors started using the astrolabe and the compass to find routes they could follow to reach faraway places and return safely home. More accurate maps allowed sailors to sail from one port to another without having to stay right along the coast. Before these advances, most sailors avoided the open sea out of fear they might not find their way back to land.
