Eduard Meyer

“ On his coins he wears an elephant’s skin with trunk and teeth on his head; on bronze coins, which have also an Indian legend in Kharoshti letters (see Bactria) , he calls himself the unvanquished king (Βασιλέως ἀνικήτου Δημητρίου) . One of his coins has already the square form used in India instead of the circular. Eventually he was defeated by the usurper Eucratides (q.v.) , who meanwhile had risen to great power in Bactria. About his death we know nothing; his young son Euthydemus II. (known only from coins) can have ruled only a short time. ”
