Title: Galileo, the Pleiades from Sidereus Nuncius (The Sidereal Messenger), Venice, 1610
Original Format: photograph: negative
Description: The observation of the Pleiades and of the previously invisible stars nearby was made possible by Galileo’s new telescope, presented to the scholars of Venice during the summer of 1609. In his published illustration of 1610 he outlined the stars that were already known and represented the others by single lines. He also tried to preserve the distinction in size.
