Shani is a deva and son of Surya and his wife Chhaya, hence also known as Chayyaputra. He is the elder brother of Yama, the Hindu god of death, who in some scriptures corresponds to the deliverance of justice. Surya's two sons Shani and Yama judge. Shani gives us the results of one's deeds through one's life through appropriate punishments and rewards; Yama grants the results of one's deeds after death. Pierre Sonnerat (1748-1814) was a French naturalist and explorer who made several voyages to Southeast Asia between 1769 and 1781. He published this two-volume account of his voyage of 1774-81 in 1782. Volume 1 deals exclusively with India, whose culture Sonnerat very much admired, and is especially noteworthy for its extended discussion of religion in India, Hinduism in particular. Volume 2 covers Sonnerat's travels to China, Burma, Madagascar, the Maldives, Mauritius, Ceylon (present-day Sri Lanka), Indonesia, and the Philippines. The book is illustrated with engravings based on Sonnerat's drawings. Among the most interesting illustrations are Sonnerat's pictures of various Hindu deities. Sonnerat was also a dedicated ornithologist and bird collector, and the book describes and depicts a number of species that he was the first to identify.
