This paper presents an overview of the dramatis personae et situs, or significant characters and places dealt with in this book. Several geographical and political maps, and timelines are provided as an aid to the reader. 1. Introduction The transits of Venus are landmarks in the history of science, principally because of their use in historical attempts to measure the scale of our solar system. Eight transits of Venus have occurred since the prediction of the first such event by Jo- hannes Kepler in 1629. These transits appeared in four pairs spaced by 8 years, with each pair separated by a time interval of more than one century.1 The transit pairs alternatively happen in early June and in early December. Figure 1 shows the timeline of occurrence of the events, together with the publication date of four historical works that played a crucial role in the transit of Venus science, viz., 1. In 1629, Johannes Kepler published in his De raris mirisq[ue] Anni 1631. Phaenomenis, Veneris put`a& Mercurii in Solem incursu,2 the very first pre- dictions that a transit of Mercury will occur in November 1631, followed by a transit of Venus one month later. Kepler died a year before the events. 2. Isaac Newton’s Philosophiae naturalis principia mathematica, that layed down the theoretical basis for Kepler’s laws, was published in London in 1687.
