Odon Lafontaine continues on with his study of the coins from the 7th century. 1) In the West he points to a copper 'fals' coin from 644-656, which according to the SIN would have been in the time of Uthman, yet it was minted in Syria, and was a copy of the Byzantine fals pattern. It has an emperor's figure on it, but shows Christian crosses, proving that these Arab rulers were auxiliaries of the Byzantines, proving that it was the Byzantines and not the Muslims who were in power in the Western areas of the Arab's control. 2) In the East, between 651-661 we find silver Drachmas minted by an Arab governor in Persia with the emperor Yazdgard III's image on the obverse and the Zoroastrian fire altar on the reverse, along with the typical crescent-moon and star pattern, proving that in the East it was the Zoroastrians and not any Muslims who were in control. Around this time a similar silver Drachma was minted but with the Arabic 'bismillah' (which means 'in the name of Allah') written on the outside, yet covered with Zoroastrian symbolism, proving that the name 'Allah', in Arabic was used by all religions at that time. 3) From 661-684, during the reign of Mu'awiya, the first of the Umayyad kings (not a Caliph, as that word had not been coined), we find copper fals in the West with Byzantine empire patterns. They depict a Byzantine emperor standing holding a cross in his hand with another cross on his crown, and a third cross on the reverse side. On the front the 'bismillah' is inscribed in Arabic, proving that even during the time of Mu'awiya, he continued to employ Christian symbols, without any Muslim emblems whatsoever. Odon believes that the 'Bismillah' suggests that Mu'awiya, who has prayed in the Church of the Sepulcher in Jerusalem, was now claiming the messianic authority which had earlier been reserved for Jesus, in order to give himself religious credibility. 4) In 663 in the West we find the Gadara Inscription (from Hamat Gader), written in Greek, with Mu'awiya's name inscribed alongside a cross, referring to him as the 'Abdallah' (servant of God) and the 'amir al-mu'minin' (commander of the believers), once again a Christian king claiming messianic authority as God's servant over the believers. 5) In 673-674 on a silver Drachma in the East Mu'awiya introduces both the 'bismillah' in Arabic, and 'amir al-mu'minin' in Persian alongside Zoroastrian emblems. 6) In 678 an inscription from the Dam of Ta'if (south of Yathrib) Mu'awiya again refers to himself as a 'servant of God' and the 'commander of the believers, suggesting that he was the intermediary between God and man, which is a messianic function. 7) Between 678-680 Mu'awiya mints a Gold Solidus. On the obverse is a "de-Christianized" picture of the Emperor Heraclius and his two ... https://www.youtube.com/watch?v=53hjaumtSYw
