GLASS:
The Phoenicians did not invent glass. However, a Phoenician glass maker is credited with inventing the free-blowing technique (which means to make the glass more transparent) sometime around 50 B.C.
Ship Building:
The Phoenicians were expert sailors who are credited with discovering how to use the North Star to direct their way. As a result of this discovery, the Phoenicians could sail on the open seas and in the ocean and they no longer had to use the coastline to help them navigate. Phoenician sailors passed this information on to the Greeks and other Mediterranean cultures.
The Alphabet:
The Phoenicians were responsible for spreading the alphabet to other cultures living along the Mediterranean, including to the Greeks. The Phoenician alphabet represented a major advance over pictograph writing techniques, such as cuneiform, and is the foundation for the writing system used by some modern Western societies.
