In 450 bc who developed a map that showed the mediterranean and 3 continents

The answer is - Herodotus.

Herodotus was the man that in 450 BC made a ''world map'' in which he has represented three continents, and the main focus is on the Mediterranean. On this map the three continents displayed are Europe (Europa), Asia, and Africa (Libya). Most of the European continent (named Europa) is shown on the map, and only the northern part of Europe is lacking on it. Asia is represented till India and Central Asia, and again the northern part is lacking in here as well. Africa (named Libya) is shown only with its northern part that is on the Mediterranean, while most of the continent is lacking on it. Herodotus managed to depict the world he knew than and he managed to do a solid job, especially because the precision is relatively good.

the discoverers and explorers: 1. natives showed jedediah smith the way. 2. william sublette was the first cross it with a caravan. 3.joel walker and his family were the frist settlers to use it. the jumping off point: 1. founded in 1827 near where the missouri river flows into the mississippi. 2. by the 1840's, it was the most popular "jumping off" point for pioneers to stock their wagons with supplies. 3. missionaries from the church of jesus christ of latter day saints attempted to make independence their zion, or holy capital. the route west: 1. the first emigrants to oregon came by ship before the trail was established. 2. ships continued to to travel to oregon even after the overland migrations began, but they were not popular among the pioneers. 3. the fare for a sea journey to oregon was quite expensive--few pioneer families could afford it. i don't know the other three i'm sorry.
