Phoenician Navigators, 600 BCE introduced the 22 Letter Semitic AlphabetTraders, colonists and sailors spread the 22-letter North Semitic alphabet, becoming the source of almost every script used in the world today (besides those of the Far East).What are the 22 autiot (symbols) now known as Hebrew?(Edit 2 on 20.Oct.19)A number of related alphabets developed within a very large region and a great mix of people, with various beliefs, passions and purposes. Gradually those alphabets were refined and an underlying thread of logic, mathematical principle, and human gesture were recorded and passed on, some forgotten, some lost, much preserved.Today, Hebrew seems to capture the most accurate recording of ancient alphabet evolution, with Greek and Arabic coming from the same heritage.The descendents of the Canaanites, the Phoenicians, are generally credited with inventing the 22-letter alphabet letters, each representing a sound, at about 1300 BCE.At this point we have to point out that the alphabet we call Hebrew today is, strictly speaking, not Hebrew at all.About the end of the sixth century BCE the Hebrew language discarded the ancient Hebrew letters and adopted Aramaic ones. This dramatic act is documented in the books of Ezra and Nehemiah in the Bible and commented on in the Talmud and in Greek sources.Source: https://www.haaretz.com/jewish/.premium-why-hebrew-should-be-called-jewish-1.5316745
