Siyâvash (, via Middle Persian Siyâwaxš, from Avestan Syâvaršan) or Siyâvoš or Siavash (), is a major figure in Ferdowsi's epic, the Shahnameh. He was a legendary Iranian prince from the earliest days of the Iranian Empire. A handsome and desirable young man, his name literally means "the one with black stallions". Ferdowsi, the author of the Book of Kings, (Shahnameh), names his horse Shabrang Behzād () literally "night-coloured purebred".

As a young man well-versed in the arts of war, he is granted entry to court by his father, Kay Kāvus, the shah of Iran. However, his stepmother, Sudabeh, the Queen of Iran, develops a burning lust for him. Refusing her advances, Siavash will have nothing to do with her stratagems to lure him into intercourse. She fakes a rape and abortion scene and blames the double calamity on Siavash who is forced to prove his innocence by riding through a colossal mountain of fire. Despite his proven innocence, the Shah eventually grows cold towards Siavash as he does not want to punish the woman he loves or anger her father, a powerful ally in the East. Siavash finds no alternative but to go into self-imposed exile in the mythical land of Turan, and seek shelter under the rule of Afrasiab, the tyrannical arch enemy of the Iranian Shah. Finally, Siavash is beheaded by Afrasiab's henchmen. His wife manages to escape to Iran, where her son becomes the next Shah, Kay Khosrow. Finally, Shah Kay Khosrow takes a terrible revenge on Afrasiab and inflicts a heavy defeat on the Turanian army.

Siyâvash

Siavash is the symbol of innocence in Iranian literature. His defence of his own chastity, self-imposed exile, constancy in love for his wife, and ultimate execution at the hands of his adopted host have become intertwined with Iranian mythology and literature over the past millennia. In Iranian mythology, his name is also linked with the growth of plants.

Early life

Iranian knights discover a beautiful young woman while on a hunting trip, a favourite pastime of the army hierarchy. They cannot decide on who should possess her for his own pleasure, and a major dispute erupts between them. Finally, they decide to take her to the Shah, Kay Kāvus, for his judgement, but the Shah decides to keep her as his own concubine and Siyâvash is the result of their union. However, as Siyâvash's mother is not an aristocrat, the Shah decides to send him to Rostam, the ultimate hero of Iranian mythology, for training in the military arts.

Siyâvash

Rostam instructs the young Siyâvash in the arts of riding, archery, hunting, conduct and speaking the truth, these being the fundamentals in the Acheamenian system of education - as reflected in the Shahnameh on several occasions. After several years of instruction, Siavash asks Rostam's permission to return to Kay Kāvus's Court, so that he may prove his worth as a young prince.

At first, Siavash is well received at Court. The ladies swoon over his youthful good looks, while the men are impressed by his mastery of the arts. The Shah even appoints him Ruler of Ctesiphon, the ancient capital of the Parthians (now situated near Baghdad). The Queen, Sudabeh, develops an instantaneous, and all-consuming sexual desire for the young prince, and starts a series of plans to entice him to enter her chambers. She praises Siavash in front of the Court, and invites him to "visit his sisters," and become better acquainted with them. Siavash is not impressed with this proposal and suspects an ulterior motive. The Shah, well-aware of his own queen's connections (she is the daughter of the Shah of Hamavaran) insists that Siavash listen to his "mother" and visit his sisters. In her chambers, the Queen organises a magnificent reception for Siavash . He is seated on a throne, expensive perfumes are lavished upon the chamber, and the ladies sing and dance for his pleasure.

The Shah decides that Siavash should marry one of the ladies, and orders him to choose one immediately, but Siavash refuses to do so, sensing his father's plans for a political union under the guise of marriage. The Queen can no longer control her desire for Siavash. She proposes to have her husband, the Shah of Iran, murdered so that she and Siavash can rule together, but he absolutely refuses to have anything to do with her. Queen Sudabeh realises that Siavash might reveal her plans to her husband, resulting in her certain death.
