An ancient Sangam Tamil literary work, Purananooru or Purananuru is a collection of poems, dating from 100 B.C. to 220 A.D. It is one of the oldest Tamil anthologies. The collection has 400 verses composed by more than 150 poets. The poems focuses on topics related to war, beauty, culture, ethics, God worship, vows of kings, courtesy, bravery, words of wisdom for kings, civilization and all aspects of day-to-day living.

The Purananuru is beyond its importance for understanding the development of South Asia`s history, culture, religion, and linguistics. It has a universal appeal. It faces the world as a great and unsolved mystery, delving into living and dying, despair, love, poverty and the changing nature of existence. Attempts have been made to assign an earlier date to some poems of the Purananuru, based on the events it records. For example, poem two in the Purananuru describes a Chera king sending food supplies to the warring sides in the Mahabharata war`s Kurukshetra battlefield (c.900 B.C.). It also mentions an invasion of a Magadha king successfully driven back (c.480 B.C.), and an unbeatable alliance of Tamil kings which stopped the Mauryan attack in 272-271 B.C. (king Kharavela of Kalinga mentions in a stone inscription of 157 B.C. that he broke that alliance which had lasted for 113 years). These early dates are, however, generally not accepted by critical scholars.

`Puram` Poetry
There are some ` arruppatai` or guide-songs in the two anthologies, Purananuru and Patir-ruppattu. In these, the poet, either a musician or dancer or actor (panan, virali or kuttan) who has received gifts from a generous patron guides another poet suffering from poverty and directs him to the same patron for help. Descriptions of the way to the city of the patron and praises of his endearing qualities abound in such guide-songs. In Purananuru, there are seven poems as guide-songs of the musicians, four of the women dancers, and three of the literary artists. Patitrruppattu contains one guide-song of the musician and five of the women dancers. All of them are in accordance with the exposition of Tolkappiyanar regarding the form of such songs.

The laments in Purananuru are frankly personal and are high tributes to the dead patrons and friends. A few of them extended to be poems of some philosophical significance. They are the outpourings of the emotions of the poets who were very attached to the patrons. The historical evidence furnished by the poems of Purananuru tallies with that of the inscriptional records and hence is valuable. It provided ample reference to the Pandya king, Palyagasalai Mudukudumi Peruvaluthi, authenticating the possibility of Pandya connection with North India at the same time being the pioneering patrons of Tamil. It sheds light on battle of Talayalankanam and Puram and also refers to the duties of various people and that of a son in a family.

The expression vilunirveli nadu kilavone occurring in Pumnanuru depicts agricultural prosperity in Sangam times. Homage is paid to the art of weaving in Puram 383 and reference is made to carded cotton of fine variety in Puram 125. Knowledge of six-system philosophy, the emphasis on dharma and justice and awareness of Buddhist and Jain philosophy is evident in Puram 28 and 358. Purananuru is very valuable not only as a great literary work but as a mirror to Tamil society, reflecting its rich traditions.
