Explanation:

These are two of the five epics of Tamil Literature that are considered in high regard by the Tamil community.
The Silappatikaram is a poetic rendition with details of Tamil culture; its varied religions; its town plans and city types; the mingling of different people; and the arts of dance and music. A poet- prince from Kodungallur near Kochi (part of ancient Tamilakam, now in modern Kerala), referred to by the pseudonym Ilango Adigal, is credited with this work.
The epic revolves around Kannagi, who having lost her husband to a miscarriage of justice at the court of the Pandyan Dynasty, wreaks her revenge on his kingdom.
Manimekalai, by the poet Chithalai Chathanar, is a poem in 30 cantos. Its story is a sequel to another of the Five Great Epics, Silappatikaram, and tells the story of the daughter of Kovalan and Madhavi, who became a Buddhist Bikkuni.
