The Sangam literature is categorized into two: love or inner (Akam) or public life or outer (Puram). A verse from the 69th poem of
Akanaṉūṟu : "விண்பொரு நெடுவரை இயல் தேர் மோரியர் பொன் புனை திகிரி திரிதர குறைத்த அறை இறந்து அகன்றனர் ஆயினும், எனையதூஉம் நீடலர் வாழி தோழி!" The verse speaks about the elegant chariots on which the
Mauryans rode through mountains and valleys and are referred to as "moriyar". These anthologies are significant source of cultural and historic information about ancient Tamil Nadu and South India.
Akaval metre Of the eight anthologies five are on Agam, two on Puram, and one on both. Six of them are in '
agaval' metre which is a kind of verse, interspersed with
alliterations and
rhymes. The poems on Agam as well as Puram theme are written in this metre and its regulated and subtle music adds to the poetic beauty. This metre is a simple but wonderful instrument, which causes no impediment to the freedom of expression of the poet. It has been found to be an appropriate and natural medium for the expression of the valuable experience of the poets.
Kali metres The other two anthologies that are not written in agaval metre are
Kaliththogai and
Paripaatal. The poems of Kaliththogai are in Kali metre which is known for its dramatic and lyrical qualities and which, according to
Tolkappiyam is well suited to express the emotions of the lovers. There is repetition of certain lines and phrases and this, added to the haunting music of the metre, is very appealing.
Paripaadal metre Paripaadal is a metre full of rhythm and music and the anthology known by this name consists of songs composed in this metre. There are religious poems as well as those on love-themes. The love-theme is worked against the background of bathing festivities. These songs were sung in different tunes as is evident from the notes on the music at the end of these. The names of the musicians who set tunes to these songs are also mentioned therein. == Religion in the Eight Anthologies ==
