This translation of Brihath Jathaka by N Chidambram Iyer has been long out of print and not many know of this commentary. The interesting part of this commentary is that he gives the meaning of the verses and then adds his own notes on the text. At some places these are extensive. Also he has converted these text into modern mathematical models in degrees and minutes and has attributed the data to degrees and minutes. Also he has compared the indian system of nomenclature to western system as well. The appendix to the translation contain numerous tables and diagrams relating to the construction of horoscopes.
