This raises the question about Jacob, did he arrogate Esau's blessing? My take is yes.

geocentric


geocentric - adj - Relating to, measured from, or with respect to the center of the earth; Having the Earth as a center.

The solar system and the "fixed stars" were believed to orbit geocentrically, meaning that they revolved around the Earth. The main proponent of this view was Ptolemy (Claudius Ptolemaius) of Alexandria (c. 90 - c. 168, see illustration), who expounded on the geocentric theory in his Almagest, one of the greatest intellectual works in history - it's only failing being that it's wrong. Polish canon Nicolaus Copernicus (1473-1543) was the first to put forth the heliocentric theory, viz., that the Earth and other planets revolved around the sun in his book De Revolutionis Orbium Coelestium (On the Revolutions of the Heavenly Bodies). That was a step in the right direction, but Copernicus and later Galileo Galilei (1564-1642) believed that the planetary orbits were circular. It was Johannes Kepler (1571-1630) who finally demonstrated that the orbits were elliptical.
