context: The Book of Shahname (Kings) is an epic poem by Persian poet Hakīm Abu'l-Qāsim Firdawsī Tūsī aka Ferdows (940 / 41- 1020) and a national epic of the Persian-speaking peoples. The book contains the true history of the kings of ancient Persia, but also a wealth of folklore and legends. The central character connecting the stories is the fabled warrior Rostam. According to some sources, it took Ferdows 35 years to write Shahnâmé. With 62 stories, 990 chapters and nearly 60,000 chapters, the work is one of the most remarkable works in Persian literature as well as world literature. It is twice as large in size as the Homeric epics, and twenty times larger than the medieval heroic epic of Nibelueg. Professor Jaakko Hämeen-Anttila has translated the work into Finnish (Otava 2016).
