The Gradeshnitsa tablets (Bulgarian: Плочката от Градешница) or plaques are clay artefacts with incised marks. They were unearthed in 1969 near the village of Gradeshnitsa in the Vratsa Province of north-western Bulgaria. Steven Fischer has written that "the current opinion is that these earliest Balkan symbols appear to comprise a decorative or emblematic inventory with no immediate relation to articulate speech." That is, they are neither logographs (whole-word signs depicting one object to be spoken aloud) nor phonographs (signs holding a purely phonetic or sound value)." The tablets are dated to the 5th millennium BC and are currently preserved in the Vratsa Archeological Museum of Bulgaria. In 2006, these tablets were the subject of attention in Bulgarian media due to claims made by Stephen Guide, a Bulgarian American of the Institute of Transcendent Analysis, Long Beach, California, who claimed he had deciphered the tablets.
