In the year 570 CE, a Persian physician named Burzoy or Burzoya (Burzawayh in Arabic) living in the Sassanid kingdom of Persia travelled to India in search of a book of wisdom: a book greatly sought by then King of Persian Khusroy I (Anoshagruwa or “the immortal”) who ruled from 531 to 579 CE. Burzoy succeeded in his endeavours, returning to Persia with the knowledge he had gained. His book was in turn written down by the king’s wazir, Wuzurgmihr and included, at Burzoy’s own request, the story of his journey to India.
