  Clemency Montelle (Univ. of Canterbury)
  The Parvadvayasādhana of Mallāri : A short treatise for computing eclipse phenomena
  The Parvadvayasādhana of Mallāri is a short text composed in the late 16th century for computing the circumstances and features of lunar and solar eclipses. The text is made up almost entirely of versified numerical data, however most manuscript copies include graphical tables alongside the verses. We consider this feature of the work, and many others : the underlying algorithms and their connection to other authors, the way in which metrological units are expressed, and the accompanying commentaries to this text which include historical worked examples with diagrams illustrating the progress of the eclipse.
