Linear A and Linear B are the names given to two sets of scripts from ancient Greece. A third known writing form of the time is Cretan Hieroglyphic. The Linear A script was used by the Minoan civilisation, which flourished on the island of Crete, whilst the Linear B script was used by the Mycenaean civilisation, which was centred on the Greek mainland. All three of these scripts were found in the same location at Knossos. Whilst Linear A has yet to be deciphered, Linear B has been found to be the oldest preserved form of written Greek that we know of at present.
