The Purananuru (Tamil: புறநானூறு, Puṟanāṉūṟu, literally "four hundred [poems] in the genre puram"), sometimes called Puram or Purappattu, is a classical Tamil poetic work and traditionally the last of the Eight Anthologies (Ettuthokai) in the Sangam literature. It is a collection of 400 heroic poems about kings, wars and public life, of which two are lost and a few have survived into the modern age in fragments. The collected poems were composed by 157 poets, of which 14 were anonymous and at least 10 were women. This anthology has been variously dated between 1st century BCE and 5th century CE, with Kamil Zvelebil, a Tamil literature scholar, dating predominantly all of the poems of Purananuru sometime between 2nd and 5th century CE. Nevertheless, few poems are dated to the period of 1st century BCE.
The Purananuru anthology is diverse. Of its 400 poems, 138 praise 43 kings – 18 from the Chera dynasty, 13 Chola dynasty kings, and 12 Early Pandya dynasty kings. Another 141 poems praise 48 chieftains. These panegyric poems recite their heroic deeds, as well as another 109 poems that recount deeds of anonymous heroes, likely of older Tamil oral tradition. Some of the poems are gnomic in nature, which have attracted unrealistic attempts to read an ethical message, states Zvelebil. The poetry largely focuses on war, means of war such as horses, heroic deeds, widowhood, hardships, impermanence, and other effects of wars between kingdoms based along the rivers Kaveri, Periyar and Vaigai.
