The book that served as the textbook of math, in India, and outside, for many centuries, now presented in a graphic novel format with 106 illustrated panels. The word problems in Lilavati invoke bees and flowers, kings and gods to describe exercises in Linear and Quadratic Equations, Progressions, Combinations and Geometry.

This book is a geometrical survey of the Sanskrit and Prakrt scientific and quasi-scientific literature of India, beginning with the Vedic literature and ending with the early part of the 17th century. It deals in detail with the Sulbasutras in the Vedic literature, with the mathematical parts of Jaina Canonical works and of the Hindu Siddhantas and with the contributions to geometry made by the astronomer mathematicians Aryabhata I & II, Sripati, Bhaskara I & II, Sangamagrama Madhava, Paramesvara, Nilakantha, his disciples and a host of others. The works of the mathematicians Mahavira, Sridhara and Narayana Pandita and the Bakshali Manuscript have also been studied. The work seeks to explode the theory that the Indian mathematical genius was predominantly algebraic and computational and that it eschewed proofs and rationales. There was a school in India which delighted to demonstrate even algebraical results geometrically. In their search for a sufficiently good approximation for the value of pie Indian mathematicians had discovered the tool of integration. Which they used equally effectively for finding the surface area and volume of a sphere and in other fields. This discovery of integration was the sequel of the inextricable blending of geometry and series mathematics.

The fifth and most popular book of the Ramayana of Valmiki, the Sundarakanda, recounts the adventures of the monkey hero Hanuman in leaping across the ocean to the island citadel of Lanka. Once there, he scours the city for the abducted Princess Sita. The poet vividly describes the opulence of the court of the demon king, Ravana, the beauty of his harem, and the hideous deformity of Sita's wardresses. After witnessing Sita's stern rejection of Ravana's blandishments, Hanuman reveals himself to the princess and restores her hope of rescue. The great monkey then wreaks havoc on the royal park and fights a series of hair-raising battles with Ravana's generals. Permitting himself to be captured by the warrior Indrajit, Hanuman is led into the presence of Ravana, whom he admonishes for his lechery. His tail is set ablaze, but he escapes his bonds and leaping from rooftop to rooftop, sets fire to the city. Taking leave of Sita, Hanuman once more leaps the ocean to rejoin his monkey companions. This is the fifth volume translated from the critical edition of the Valmiki Ramayana. It contains an extensive introduction, exhaustive notes, and a comprehensive bibliography.
