Indian archaeologist Shikaripura Ranganatha Rao claimed to have deciphered the Indus script. He compared it to the Phoenician alphabet, and assigned sound values based on this comparison. His decipherment results in an "Sanskritic" reading, including the numerals aeka, tra, chatus, panta, happta/sapta, dasa, dvadasa, sata (1, 3, 4, 5, 7, 10, 12, 100).[50] He also noted a number of striking similarities in shape and form between the late Harappan characters and the Phoenician letters, arguing that the Phoenician script evolved from the Harappan script, and not, as the classical theory suggests from the Proto-Sinaitic script.[51]
