INTRODUCTION



Acyuta, the author -

 Acyuta is a prominent figure in the literary annals of Kerala where he is well known under his full name Trikkantiyur Acyuta Pisarati. “Tr-k-kanti-y-ar' (often Sanskritised into 'Sri-Kunda-pura'), situated near Tirur in South Malabar, was his home-town, and "Pisarati' was his surname indicating his caste, being one of the external functionaries of the Kerala temple. He was a profound scholar, especially in astronomy and grammar. He wielded a facile pen and some of his verses, particularly the illustrative verses added to his work Pravesaka, form exquisite pieces of poetry. Besides, he was proficient also in Ayurveda, as known from a pointed reference thereto by his famous pupil, Melputtur Narayana Bhattatiri, in an obituary verse composed by him at the demise of Acyuta ;

हे शब्दागम ! निर्दय विबुधतालुब्धैनिपीडिष्यसे
धाष्टचेंकप्रवणासि वैद्यसरणे ! नष्टोऽस्यलङ्कार भोः ! ।
हन्त ज्योतिषतन्त्र ! पर्यवसिता तिथ्यूक्षयोस्ते कथा
‘विद्यात्मा स्वरसंपद् ’ अत्रभवतामाधारभूर् अच्युतः ॥
