Agni Purāṇa

335 - The tabular representation of long andshort vowels of different metres

The  Purāṇa summarises the first sütra and the concluding sâtras 24-34 of Pingala ch. VIII. The verses are very cryptic. Verscs 3 and 4 have not been transtated.

Agni said:

1. That which has not been described in the treatises on metrics is known as Gåthå. All syllables in a quarter would be long. The next one is made one (mätra) less and the rest the same as the previous. 

2. If the mark in the middle of the metre) to be known is equal, the first letter would beshort. If it is unequal it is long. Ifshould then be made as half unequal. If it is the reverse the first letter would beshort. When two are desired one will be reduced.
