Rudaba

Rudāba or Rudābeh ( ) is a Persian mythological female figure in Ferdowsi's epic Shahnameh. She is the princess of Kabul, daughter of Mehrab Kaboli and Sindukht, and later she becomes married to Zal, as they become lovers. They had two children, including Rostam, the main hero of the Shahnameh.
Etymology.
The word "Rudābeh" consists of two sections. ""Rud" and "āb", "Rud" means "child" and "āb"" means "shining", therefore means "shining child" (according to Dehkhoda Dictionary).
Marriage to Zal.
The Shahnama describes Rudaba with these words:
It was this description and Rudaba's physical beauty that initially attracted Zal. Rudaba also consulted her ladies-in-waiting about Zal. Zal came to the walls of Rudaba's palace where Rudaba let down her tresses to Zal as a rope and he immediately climbed from base to summit. Rudaba seated Zal on the roof and they both talked to each other for a long time. Although such actions were seen as unacceptable according to Islamic traditions, it was nevertheless the cultural norms of Iran that Ferdowsi wanted to highlight.
Zal, consulted his advisors over Rudaba. They at last advised him to write a full account of the circumstances to his father, Sam. Sam and the Mubeds, knowing that Rudaba's father, chief of Kabul, was Babylonian from the family of Zahhak, did not approve of the marriage. Zal reminded his father of the oath he had made to fulfill all his wishes.
Finally, the ruler referred the question to astrologers, to discover whether the marriage between Zal and Rudaba would be prosperous or not and he was informed that a child of Zal and Rudabeh would be the conqueror of the world. When Zal arrived at the court of Manuchihr, he was received with honour, and having read the letter of Sam, the Shah approved of the marriage.
The marriage took place in Kabul, where Zal and Rudaba first met each other.
Motherhood.
In Persian mythology, Rudabeh's labor of Rostam was prolonged due to the extraordinary size of her baby. Zal was certain that his wife would die in labor. Rudabeh was near death when at last Zal recollected the feather of the Simurgh, and followed the instructions which he had received, by placing it on the sacred fire. The Simurgh appeared and instructed him upon how to perform a caesarean section ("rostamzad"), thus saving Rudabeh and the child, who later on became one of the greatest Persian heroes.
Legacy.
An English translation of the story exists in "The story-book of the Shah; or, Legends of old Persia", in prose format.
Scholarship points that the love story of Zal and princess Rudabah is related to an Afghan folktale tale named "The Romance of Mongol Girl and Arab Boy".
It has been noted by folktale collectors that Rudabah's long hair and the climbing incident are very reminiscent of the German story of Rapunzel.
