No small portion of the data presented in the following sections has already been taken up and explained in the works mentioned at the end of this section, but I newly collected the data from the original sources and arranged them in my own way according to my own interest.</p> 2017-07-03T09:52:40-06:00 ##submission.copyrightStatement## Notes on Some Sanskrit Astrological Authors 2017-12-22T23:38:58-07:00 Martin Gansten <p class="western">This paper supplements and corrects the information given in the works of David Pingree regarding four major authors on Tājika or Sanskritized Perso-Arabic astrology from the fourteenth to the seventeenth century: Tejaḥsiṃha, Yādavasūri, Bālakṛṣṇa and Balabhadra. It further contributes information on a fifth such author, Tuka, not discussed by Pingree.</p> 2017-08-19T08:59:49-06:00 ##submission.copyrightStatement## The Bakhshālī Manuscript: A Response to the Bodleian Library's Radiocarbon Dating 2017-12-22T23:38:58-07:00 Kim Plofker Agathe Keller Takao Hayashi Clemency Montelle Dominik Wujastyk <p>Popular attention has recently been captured by the results of the Bodleian Library's 2017 project of radiocarbon dating portions of the birch-bark fragments constituting what is known as the Bakhshālī Manuscript.  In this paper, we disagree with the interpretation of the findings announced by the Bodleian team. In particular, we argue that the earliest dated folio of this manuscript is unlikely to be the date of the whole text. Rather, the latest dateable folio is logically the date of the scribal activity. This fits well with past estimates of the date of the Bakhshālī Manuscript based on historical, philological and palaeographic arguments..  And we argue that the Bakhshālī Manuscript does include written zeros that function as arithmetical operators, i.e., as numbers in their own right, and not merely as place-holders, as asserted by the Bodleian team. Finally, we express regret that the Bodleian Library chose to announce scientific results without peer-review and through a press release to newspapers and a YouTube video.</p> 2017-10-06T15:40:59-06:00 ##submission.copyrightStatement## Garga and Early Astral Science in India 2018-01-03T11:01:08-07:00 Marko Geslani Bill Mak Michio Yano Kenneth G. Zysk <p>This article forms a preliminary report on the work by an international group of scholars on Garga, an important early authority on astral science (jyotiṣa). Reviewing past research on the texts associated with this figure, we focus especially on the earliest text, the Gārgīyajyotiṣa (ca. first century CE?), a compendium of material on astral and terrestrial omens, ritual, horoscopy, and astronomy, that prefigures Varāhamihira's well-known Bṛhatsaṃhitā. The contributions include text-critical observations based on select chapters, remarks on astral omens and their relevance to the possible dating of the text, and a discussion of the text's potential for the study of Hindu ritual. The article also begins to disambiguate the broader Garga corpus by including a chapter summary of a somewhat later Gargasaṃhitā, containing mainly astronomical materials.</p> 2017-12-22T23:33:07-07:00 ##submission.copyrightStatement##
