The day the Greeks invented vowels - History of Writing Systems #8 (The Alphabet)

Your vowels were invented in Greece, giving birth to the first "true" alphabet. Watch as your new toga-clad friend turns your consonant abjad into a consonant-vowel alphabet. It's such a useful mapping of letters to sounds that neighbor civilizations borrow it left and right. It even evolves into the letters you're reading right now. As useful as the Greek alphabet is, this isn't where the history of writing ends. There are even more inventions in store for written language!
