Themes of his ghazals include the beloved, faith and exposing hypocrisy. Hafez primarily wrote in the literary genre of lyric poetry or ghazals, that is the ideal style for expressing the ecstasy of divine inspiration in the mystical form of love poems. His works can be described as " antinomian" and with the medieval use of the term "theosophical" the term " theosophy" in the 13th and 14th centuries was used to indicate mystical work by "authors only inspired by the holy books" (as distinguished from theology). Hafez is best known for his Divan of Hafez, a collection of his surviving poems probably compiled after his death. His life and poems have become the subjects of much analysis, commentary and interpretation, influencing post-14th century Persian writing more than any other Persian author. His works are often found in the homes of people in the Persian-speaking world, who learn his poems by heart and use them as everyday proverbs and sayings. Khāwje Shams-od-Dīn Moḥammad Ḥāfeẓ-e Shīrāzī ( Persian: خواجه شمسالدین محمّد حافظ شیرازی), known by his pen name Hafez ( حافظ, Ḥāfeẓ, 'the memorizer the (safe) keeper' 1315-1390) and as "Hafiz", was a Persian lyric poet, whose collected works are regarded by many Iranians as a pinnacle of Persian literature.
