Literature
Brihat Samhita of Varahamihira, translated by Chidambara Iyer
An encyclopedic compendium by the same Varahamihira: omens, architecture, gems, agriculture, the motion of the planets and comets. Not natal astrology, but it sets out the same astronomical grounds against which his parameters are checked.
Hora Sara of Prithuyasas, translated by R. Santhanam
A concise manual of natal astrology ascribed to Varahamihira's son — the author names himself, in the colophon of every chapter, the son of the immortal Varahamihira. It keeps the same frame as the Brihat Jataka but sometimes states plainly what the father only hinted at. A recognised text is available.
Jataka Parijata of Vaidyanatha Dikshita
A compendium of natal astrology in eighteen chapters, among the most quoted of the later treatises. It gathers rules scattered through the earlier sources, which makes it a convenient reference for yogas and dasas. A recognised text is available.
Brihat Jataka, Sanskrit edition
The Sanskrit text of the Brihat Jataka in Devanagari, without translation. Needed where the English translations disagree and one has to see what the original actually says.
Brihat Jataka with Bhattotpala's commentary, translated by V. Subrahmanya Sastri
The second edition, with an English translation and Bhattotpala's commentary — the oldest surviving commentary on the Brihat Jataka. Where Varahamihira's verse admits two readings, the commentator says which one the school adopted. A recognised text is available.
Brihat Jataka of Varahamihira, translated by Swami Vijnanananda
An English translation of Varahamihira's principal treatise on natal astrology — the sixth-century compendium on which nearly every later work of the school depends. Twenty-eight chapters, from the nature of the signs to the reconstruction of a lost horoscope. A recognised text is available for searching.
