Appar, also referred to as Tirunāvukkarasar (Tamil: திருநாவுக்கரசர்) or Navukkarasar, was a seventh-century Tamil Śaiva poet-saint. Born in a peasant Śaiva family, raised as an orphan by his sister, he lived about 80 years and is generally placed sometime between 570 and 670 CE. Appar composed 4,900 devotional hymns to the Hindu god Shiva, out of which 313 have survived and are now canonized as the 4th to 6th volumes of Tirumurai. One of the most prominent of the sixty-three revered Nayanars, he was an older contemporary of Thirugnana Sambandar.
