"Support for this idea of pre-Ashokan development has been given very recently by the discovery of sherds at Anuradhapura in Sri Lanka, inscribed with small numbers of characters which seem to be Brāhmī. These sherds have been dated, by both Carbon 14 and Thermo-luminescence dating, to pre-Ashokan times, perhaps as much as much as two centuries before Ashoka."[9]
