Copernican heliocentric theory arises due to its apparent mathematical grandeur and his prior commitment to the theory. Marius, however, showed no evident commitment to any theory but rather hypothesized based on telescopic observation. He also concluded from his observations of the
Galilean moons that they must orbit Jupiter while Jupiter orbits the Sun. Therefore, Marius concluded that the geocentric

Capra published another book in 1607 which he actually plagiarised from
