Casual stargazers are familiar with many classical figures and asterisms
composed of bright stars (e.g., Orion and the Plough), but this book
reveals not just the constellations of today but those of yesteryear.
The history of the human identification of constellations among the
stars is explored through the stories of some influential celestial
cartographers whose works determined whether new inventions survived.
The history of how the modern set of 88 constellations was defined by
the professional astronomy community is recounted, explaining how the
constellations described in the book became permanently "extinct." Dr.
Barentine addresses why some figures were tried and discarded, and also
directs observers to how those figures can still be picked out on a
clear night if one knows where to look. These lost constellations are
described in great detail using historical references, enabling
observers to rediscover them on their own surveys of the sky. Treatment
of the obsolete constellations as extant features of the night sky adds
a new dimension to stargazing that merges history with the accessibility
and immediacy of the night sky.
