Postcard: Christoph Scheiner, Macvlae in sole aparentes observatae (Spots observed appearing on the sun) (1630)

$2.00

Christoph Scheiner’s Macvlae in sole aparentes observatae (Spots observed appearing on the sun) (1630) captured the changing position of sunspots between October and December 1611. The positions are hand drawn, and Scheiner wrote that “[t]hey are not terribly exact, but rather hand drawn on paper as they appeared to the eye without certain and precise measurements, which could not be done sometimes due to inclement and inconstant weather, sometimes due to lack of time, and at other times due to other impediments.”

4″x6″ postcard with white blank back.
