Khwāja Shams-ud-Dīn Muhammad Hāfez-e Shīrāzī, also known by his pen name Hafez, was a Persian poet who rejoiced in the joys of love and wine, but also targeted religious hypocrisy. His collected works are regarded as a pinnacle of Persian literature and are to be found in the homes of most people in Iran, who learn his poems by heart and use them as proverbs and sayings to this day. His life and poems have been the subject of much analysis, commentary and interpretation, influencing post-fourteenth century Persian writing more than any other author. Common themes found in his ghazals are most often tributes to his beloved, faith, and exposing hypocrisy. His influence in the lives of Persian speakers can be found in the frequent use of his poems in Persian traditional music, visual art, rug design, and Persian calligraphy. His tomb is heavily visited often.
