Information: - The Shahnameh, also transliterated as Shahnama (, "The Book of Kings"), is a long epic poem written by the Persian poet Ferdowsi between c. 977 and 1010 CE and is the national epic of Greater Iran. Consisting of some 50,000 "distichs" or couplets (2-line verses), the "Shahnameh" is the world's longest epic poem written by a single poet. It tells mainly the mythical and to some extent the historical past of the Persian Empire from the creation of the world until the Islamic conquest of Persia in the 7th century. Today Iran, Azerbaijan, Afghanistan and the greater region influenced by the Persian culture (such as Georgia, Armenia, Turkey and Dagestan) celebrate this national epic. - Persian literature is one of the world's oldest literatures. It spans two-and-a-half millennia, though much of the pre-Islamic material has been lost. Its sources have been within Greater Iran including present-day Iran, Iraq, the Caucasus, and Turkey, regions of Central and South Asia where the Persian language has historically been either the native or official language. For instance, Rumi, one of best-loved Persian poets, born in Balkh or Vakhsh (in what is now Afghanistan), wrote in Persian, and lived in Konya, then the capital of the Seljuks in Anatolia. The Ghaznavids conquered large territories in Central and South Asia and adopted Persian as their court language. There is thus Persian literature from Iran, Mesopotamia, Azerbaijan, the wider Caucasus, Turkey, western parts of Pakistan, India, Tajikistan and other parts of Central Asia. Not all Persian literature is written in Persian, as some consider works written by ethnic Persians in other languages, such as Greek and Arabic, to be included. At the same time, not all literature written in Persian is written by ethnic Persians or Iranians, as Turkic, Caucasian, and Indic poets and writers have also used the Persian language in the environment of Persianate cultures. - The Avesta is the primary collection of religious texts of Zoroastrianism, composed in the otherwise unrecorded Avestan language. - Abu l-Qasim Ferdowsi Tusi ("c." 9401020), or Ferdowsi (also transliterated as Firdawsi, Firdusi, Firdosi, Firdausi) was a Persian poet and the author of "Shahnameh" ("Book of Kings"), which is the world's longest epic poem created by a single poet, and the national epic of the Greater Iran. Having drafted the "Shahnameh" under patronage of the Samanid and the Ghaznavid courts of Iran, Ferdowsi is celebrated as the most influential figure in Persian literature and one of the greatest in the history of literature. He is widely regarded as the greatest poet in the Persian language. He was called "The Lord of the Word" and "The Savior of Persian Language". - Hushang or Hshang ( in Persian : ) , older Persian Hsang , was the second Shh to rule the world according to Ferdowsi 's Shhnma . Hushang is based upon the legendary figure Haosyaha in the ancient Zoroastrian scripture of the Avesta . Hushang is also called Pishdd ( ) , older Psdd , corresponding to Avestan Parata . - A national epic is an epic poem or a literary work of epic scope which seeks or is believed to capture and express the essence or spirit of a particular nation; not necessarily a nation state, but at least an ethnic or linguistic group with aspirations to independence or autonomy. National epics frequently recount the origin of a nation, a part of its history, or a crucial event in the development of national identity such as other national symbols. In a broader sense, a national epic may simply be an epic in the national language which the people or government of that nation are particularly proud of. It is distinct from a pan-national epic which is taken as representative of a larger cultural or linguistic group than a nation or a nation-state. - Zoroastrianism, or more natively Mazdayasna, is one of the world's oldest extant religions, "combining a cosmogonic dualism and eschatological monotheism in a manner unique [...] among the major religions of the world". Ascribed to the teachings of the Iranian prophet Zoroaster (or Zarathustra), it exalts a deity of wisdom, Ahura Mazda ("Wise Lord"), as its Supreme Being. Major features of Zoroastrianism, such as messianism, heaven and hell, and free will have allegedly influenced other religious systems, including Second Temple Judaism, Gnosticism, Christianity, and Islam. With possible roots dating back to the second millennium BCE, Zoroastrianism enters recorded history in the 5th-century BCE, and along with a Mithraic Median prototype and a Zurvanist Sassanid successor it served as the state religion of the pre-Islamic Iranian empires from around 600 BCE to 650 CE. Zoroastrianism was suppressed from the 7th century onwards following the Muslim conquest of Persia of 633-654. Recent estimates place the current number of Zoroastrians at around 2.6 million, with most living in India and in Iran. Besides the Zoroastrian diaspora, the older Mithraic faith Yazdanism is still practised amongst Kurds. What is the relationship between 'hushang' and 'shahnameh'?
