<p style='text-align: justify;'>The work is an independent philosophical treatise on the topic of the seven categories (<i>padārtha</i>s), also known under the title <i>Padārthamaṇimālā</i>. Its author, Jayarāma Nyāyapañcānana, is the pupil of one Rāmabhadra, whose identity is still uncertain (extensive discussion in Mishra 1962: 437). He belongs to the Bengali school of Navya-Nyāya, and was active in the 17th century (Kaviraj 1961: 69). The date of copy of the manuscript, 1692 saṃvat (= 1636 AD), may thus be very close to the date of composition of the text. </p>
