This paper discusses the factors involved in the acceptability of Galileo’s theories in science & theology.

Vincenzo’s death in 1591 gave Galileo a much more worrying legacy: the financial dependence of the rest of the family. His chair in Mathematics was not enough to support what seems to have been a large family, and certainly not to provide dowries (cash payments which women brought to a marriage) for his sisters. Galileo was head of the household, and now responsible for the rest of the family. This necessity forced Galileo to leave his post at Pisa, and move to the University of Padua, in Venice.
