Neon sign

The sign is located above the entrance to Dr. Sena’s Dental Clinic – a dentist’s clinic in Doha, capital of Qatar. The crescent moon is one of the world’s oldest religious symbols, dating all the way back to 2000 BCE, when the moon used to be the symbol of the Mesopotamian god Sin. Already then, the moon would appear accompanied by a star, usually representing Sin’s daughter Ishtar, goddess of war, love, and sex, among other things. The crescent moon and the star were used as a flag by the Ottoman Empire already in the 14th century, and was later inherited by the country known today as Turkey. Since then, it has actually come to be the symbol of many other countries. In his particular version of the powerful symbol, Dr. Sena in Doha replaced the star with a molar tooth.
