The first written Greek was found on baked mud tablets. The Greek language goes all the way back to thirteenth century B.C. The most primitive form of the language is called "Linear B". The Greek used by Homer and Plato is "Classical Greek." The language was able to show exact expression and subtle nuances. Its alphabet was derived from the Phoenician’s. Classical Greek existed in many dialects of which three were primary: Doric, Aeolic, and Ionic. When the Greek language started to spread across the world and combine with other languages it started change. The dialects also interacted with each other, eventually giving us Koine Greek. Koine means common. Koine was a shortened form of classical Greek and many of the refinements of classical Greek are lost.
