The birthday of Lilit Teryan (Iranian sculptor) is observed on December 31. Lilit Teryan was a prominent figure in Iranian sculpture, born in 1930 in Tehran. She is recognized as one of the first female sculptors in Iran and played a significant role in the development and teaching of sculpture in the country. Teryan completed her studies in sculpture in France and, upon returning to Iran, began teaching at the Faculty of Fine Arts at the University of Tehran. Throughout her career, Lilit Teryan created numerous works, some of which were exhibited both in Iran and internationally. Her unique style and attention to Iranian cultural and social elements earned her a special place in the country's contemporary art scene. Teryan was also known as a mentor to many young artists, leaving a lasting impact on subsequent generations of Iranian sculptors. In 2022, her birthday was officially added to the Gregorian calendar as a commemorative event to honor her contributions to the development of sculpture and the advancement of women artists in Iran. On this day, some art centers and academic institutions hold gatherings and exhibitions to reflect on her works and artistic legacy.
