A great sailor is the one who is fearless, who loves the unknown, someone who keeps his cool when the tides are high; someone who continues the voyage until the destination is reached. Many ancient coins with ships indicate the importance of these uncertain and sometimes life-threatening missions. From ancient times, naval expeditions haven been carried out to discover new trade routes and connect with different parts of the world. Kingdoms and states always encouraged such activities, as flourishing trade meant more business which would then add to the empire’s wealth. Trade could also sometimes lead to colonization which was considered as a big fish in those days.
