Cysatus (1588-1657)
Cysatus independently discovered the
Orion Nebula M42 in 1611,
one year after its original discovery by Peiresc.
He published these observations in 1619, in his
Mathemata astronomica de cometa anni 1618.
Nevertheless, this publication and discovery fell forgotten until their
rediscovery by R. Wolf (1854); also see
M.G. Bigourdan (1916).
