Therigatha
The Therigatha (Therīgāthā), often translated as Verses of the Elder Nuns (Pāli: therī elder (feminine) + gāthā verses), is a Buddhist scripture, a collection of short poems of early women who were elder nuns (having experienced 10 Vassa or monsoon periods) from around 600 BCE [source?]. In the Pāli Canon of Theravada Buddhism, the Therigatha is classified as part of the Khuddaka Nikaya, the collection of short books in the Sutta Pitaka. It consists of 73 poems organized into 16 chapters. A recent translation has been published by Harvard University Press as part of the Murty Classical Library of India.
It is the earliest known collection of women's literature.
