Architecture
Take the Persian city as an example: the base platform is imitated from West Asia; the main hall with large stone pillars is imitated from the Egyptian temple; the grooves and spirals of the stone pillars are inspired by Greek influence; the stone lions on both sides of the palace door, the palace walls, reliefs, and glazed tiles on the roof are similar to Assyrian architecture.
Literature
Convert the 22 symbols used by the Canaanites into phonetic letters that facilitate writing and learning. After being spread to the West, they became the basis of Greek letters, Latin letters and other European letters* **The same foundation is its most outstanding contribution to culture.
As early as the 6th century BC, Cyrus, the chief of the Persian tribe in the Fars region of Iran, established the Achaemenid state, a unified slave empire. Before the 3rd century AD, ancient Persian (cuneiform) was commonly used in southwestern Iran. There are inscriptions about the achievements of King Darius (reigned from 521 BC to 485 BC) carved on the mountains near Kermanshah in western Iran. The writing is ancient Persian; the language spoken in northeastern Iran is Avestan, and there is already embryonic poetry in the Zoroastrian scripture "Avesta".
Art
In terms of art, the Persian Empire left a valuable legacy. The empire recruited laborers and construction materials from various conquered peoples to build palaces and decorate the capital. Persian architecture combines the artistic achievements of Egypt, Babylon, and Greece to form its own unique and majestic style. The palace of Persepolis, the new capital of Darius I, was built on a high platform made of huge stones. There was a hall where the king listened to politics and a hall with a hundred columns. The columns were 7.62 meters high, with sacred bulls, horned lions and human faces as capitals ( See color picture of the Audience Hall of the Palace of Persepolis). On the wall on the side of the high steps are reliefs showing a procession of thousands of immortal troops, courtiers and conquered ethnic groups paying tribute. The ruins of the palace in Susa have colorful glazed brick walls depicting the king's guards and various wild animals. All this is intended to show the greatness of the empire and the dignity of the king. Metal joinery is also a highly developed craft in Persia. Artists used the hammering method to make various animal-shaped gold pieces to decorate palace doors and utensils.
Religion
If one considers that Darius I and his immediate successor Xerxes showed in their inscriptions that they had embraced something similar to Zoroastrianism The religion of the Persian Empire, the tolerant attitude of the emperor of the Persian Empire towards foreign religions is even more commendable and unique, because the true meaning of Zoroastrianism is combat, not tolerance. In this spirit Zoroaster abandoned the traditional religion of the Iranian-speaking peoples and replaced it with a new family religion. Zoroaster believed that his mission was to spread faith in a good god, Ahura Mazda, the god of light. His faith in the God of Light is unwavering. We don’t know the extent of Darius I and Xerxes’s belief in Zoroastrianism, nor did they openly claim to be followers of Zoroastrianism, nor did they even mention his name. The prophet was born about a century earlier than Darius I, and his missionary area seems to have been in the northeastern region where Iranian-speaking peoples settled (today's Khorasan and Uzbekistan).
