This is what Revelation 13 : 11-14 said,
"11Then I saw another beast, coming out of the earth. He had two horns like a lamb, but he spoke like a dragon. 12He exercised all the authority of the first beast on his behalf, and made the earth and its inhabitants worship the first beast, whose fatal wound had been healed. 13And he performed great and miraculous signs, even causing fire to come down from heaven to earth in full view of men. 14Because of the signs he was given power to do on behalf of the first beast, he deceived the inhabitants of the earth. He ordered them to set up an image in honor of the beast who was wounded by the sword and yet lived."
It did not say to make an image of the dragon but of the beast who was wounded by the sword but yet lived. The verse probably means that one of the leading country or head of state of EU or EUNATO is severely damaged or wounded by war but survived. The image was made in commemoration of the event.
I do not know how the dragon spoke, but the verse "he spoke like a dragon" probably means that the dragon and the 2nd beast spoke in a language that is different from the Europeans perhaps Arabic or some Asian or Oriental language or perhaps with an Arabic, Asian or Oriental accent.
God Blessings to you.
