Diwan V. Nagam Aiya's work in 1906, the
Travancore State Manual is a huge volume of history (1820 pages, published in three volumes of 648, 592 and 580 pages respectively) not only on the antiquity of Travancore, but also of various other features of the place. The works along with history also contains detailed study and examination of the physical features, geology, climate, rainfall, meteorology, flora, fauna, and archaeology of Travancore State at the time. The manuals includes details such as the geographical location, boundaries, shape and area of the landscape, mountains, plateaus, mountain passes, rivers, canal and backwaters, coastline, ports, shipping facilities,
economic geology of the place, climate, rainfall, meteorology, trees, and medicinal plants, flowering and ornamental plants, birds and animals etc., archaeology, architecture, sculpture, coins, inscriptions, forts and military works, ‘Archaeology’, ‘Fauna’, census and population, language, economic condition and various other things are dealt with, in a manner that should astound. There are a number of photographs. Apart from that, there are many pictures of the stone inscriptions collected from various parts of the kingdom. The latter part of the book deals in detail on the history of the localities that were later to be joined to form Travancore kingdom. The delineation of history starts from the Parasurama legend. This legend is also mentioned in great detail. Then it slowly moves to the times of the Perumals. Mentions about the Malabar and Travancore coasts in the ancient maritime trade records are seen sourced out. Sections on history deals with the ancient kings. There is a mention of a Kurava King, who seems to have been assassinated in a premeditated conspiracy. There are other details on items such as early missionaries, neighbouring kingdoms, accounts of travellers, Portuguese in Malabar and Travancore, Ettuvittial Pillamaar, Marthanda Varma, Zamorin, small kings and kingdoms north of Travancore, small-time rulers of Malabar, the attacks and occupation attempts by Sultan Tipu etc. Velu Thampi Dalawa's rebellion is dealt with in details. Even though there is sympathy for the person, in a profound analysis, Nagam Aiya does not find his cause correct or praiseworthy. The proclamation made by Velu Thampi from Kundara is quoted in an elaborate manner. However, a full reading of the same would not find it to be in sync with modern Indian aspirations. "Velu Tampi was a daring and clever though unscrupulous man. Rebellion was his forte." "His favourite modes of punishment were: imprisonment, confiscation of property, public flogging, cutting off the palm of the hand, the ears or the nose, impalement or crucifying people by driving down nails on their chests to trees, and such like, too abhorrent to record here." All rulers of Travancore, since the reign of King Marthanda Varma are dealt in reasonable detail. Swathi Thirunal's (King Rama Varma) tragic life has been mentioned. == His goals ==
