copper mirror were found. A necklace of steatite beads strung to a copper wire with hooks at both ends, a gold bangle, gold and other beads were also found in one of the hemispherical structures. The Archaeological Survey of India, which conducted the excavation, opines that these “hemispherical structures remind one of early Buddhist stupas.” and that "the kind of design that is of spoked wheel and unspoked wheel also remind one of the Sararata-chakra-citi and sapradhi-rata-chakra-citi mentioned in the Satapatha Brahmana and Sulba-sutras". Findings Painted Indus black-on-red-ware pottery, square stamp seals, seals without Indus script, a huge signboard measuring about in length, containing ten letters of Indus script. One poorly preserved seated male figure made of stone has also been found, comparable to high quality two stone sculptures found at Harappa. Large black-slipped jars with pointed base were also found at this site. A giant bronze hammer, a big chisel, a bronze hand-held mirror, a gold wire, gold ear stud, gold globules with holes, copper celts and bangles, shell bangles, phallus-like symbols of stone, square seals with Indus inscription and signs, a circular seal, humped animals, pottery with painted motifs, goblets, dish-on-stand, perforated jars, Terracotta tumblers in good shape, architectural members made of ballast stones, grinding stones, mortars, etc., were also found at this site. Stone weights of different measures were also found. Coastal route It is suggested that a coastal route existed linking Lothal and Dholavira to Sutkagan Dor on the Makran coast. Language and script The Harappans spoke an unknown language and their script has not yet been deciphered. It is believed to have had about 400 basic signs, with many variations. The signs may have stood both for words and for syllables. The direction of the writing was generally from right-to-left. Most of the inscriptions are found on seals (mostly made out of stone) and sealings (pieces of clay on which the seal was pressed down to leave its impression). Some inscriptions are also found on copper tablets, bronze implements, and small objects made of terracotta, stone and faience. The seals may have been used in trade and also for official administrative work. A lot of inscribed material was found at Mohenjo-daro and other Indus Valley Civilisation sites. Sign board The most significant discoveries at Dholavira was made in one of the side rooms of the northern gateway of the city, and is generally known as
