The greatest similitude between zoroastrianism and judaism is their belief in good and evil. In zoroastrianism, good is represented by Ahura Mazda and evil by Ahriman, and in judaism is Yahway and Satan. Both religions took the same message and converted according to their culturual idiosincracies.
The main difference in both religions is in their concept of deidity. While judaism belief in a single God and the teachings of their rabbis and prophets, in zoroastrianism God is a good deidity battling a cosmic battle against the God of evil.
The most detailed Roman mosaics use small stones to achieve an effect like brushstrokes. Especially in the eastern provinces of the Roman empire, artists “painted” with stone. Hope this helped :)
