Query: In which year did the poet Rumi die?
Context: Many works are written in Persian such as the works of Maybudi (d. 1135) kash al-asrar ("the unveiling of the secrets"). Rumi (d. 1273) wrote a vast amount of mystical poetry in his book Mathnawi. Rumi makes heavy use of the Quran in his poetry, a feature that is sometimes omitted in translations of Rumi's work.
