Patronage in astronomy
Patronage in astronomy is an approach which one can use to examine the history of astronomy from a cultural standpoint. Rather than simply focusing on the findings and discoveries of individual astronomers, this approach emphasizes the importance of patronage in shaping the field of astronomy.
