, as some figures in the movement “were not sustained by patronage, and it is not yet clear how many were so supported.” Despite this, patronage “was perhaps the most pervasive institution of preindustrial society.”
Richard Westfall concludes:
Only now are scholars beginning to chart its course in the science of the age, and we have every reason to expect that it will prove to be very important there as well. I would like to suggest, that patronage, together with other practices that the age itself reveals to us, may be the avenue most likely to lead us into a fruitful social history of the Scientific Revolution, a movement to which the present generation of scholars has devoted itself extensively. In our investigations, it appears to me, we have allowed ourselves to be dominated excessively by concepts derived in the nineteenth century which are more applicable to that century and our own than to he eventeenth entury.. Efforts to impose them on the 17th century have appeared forced and largely barren, and I want to propose, not as a new dogmatism, but as a topic for discussion, the possibility that we need to come at the problem from a different angle, using seventeenth-century categories instead of nineteenth-century ones. Patronage was certainly a seventeenth-century category.
What is patronage?
The system of patronage in 16th- and early 17th-century astronomy was different from the modern definition of patronage. The system of patronage, in the context of Astronomers such as Galileo, Kepler, and
Copernicus
Nicolaus Copernicus (19 February 1473 – 24 May 1543) was a Renaissance polymath who formulated a mathematical model, model of Celestial spheres#Renaissance, the universe that placed heliocentrism, the Sun rather than Earth at its cen ...
, was a complex system of relations held between such astronomers and other individuals of high social standing.
left, Jupiter's moons shown from an amateur telescope These relations allowed for the likes of Galileo to hold positions under such powerful people as the Medici family, granting him not only increased social status due to his relations with such high social ranks, but entry into these positions also allowed for the time and monies to work on scientific endeavors. As important as these relationships were for patrons such as Galileo, for reasons of gaining monies and higher social status, clients also found importance in patronage from the reciprocal nature of the relationship. Gifts to be bestowed upon clients, such as the
Medici Stars given to the Medici family by Galileo (he named
Jupiter's moons after the family upon his discovery of them) gave increased social splendor and honor to the recipients of such extravagance and rarity.
Modern day photo of the Moons of Jupiter, which Galileo named the Medici Stars upon discovery The courts where these patronage relationships played out would also contribute to the “cognitive legitimation of the new science by providing venues for the social legitimation of its practitioners, and this, in turn, boosted the epistemological status of their discipline.” Although Patronage can be explained as a system of social connections and relationships amongst social elite and practitioners of what we now umbrella under the term science, it was actually a “set of dyadic relations between patrons and clients, each of them unique…
avingno institutions and little if any formal structure. Patronage embodied no guarantees, and the “relation between patron and client was voluntary on both sides and subject always to disintegration” where past “performance counted only to the extent that it promised more in the future.” Westfall notes a “client's only claim on a patron was his capacity to illuminate further the magnificence of the man who recognized his value and encouraged him.”
Viewpoint of historians
Nicholas Jardine
In his article titled ''The Places of Astronomy in Early-Modern Culture,''
Nicholas Jardine looks to examine how the system of patronage and the codes of courtly conduct shaped a new agenda for astronomy: the quest for the true world system. Jardine begins his article by noting that astronomy “did not then make up a specialty or discipline in anything like the modern sense… rather, it comprised a whole series of practices widely diffused through the various social sites and strata.” The focus of University teachings on astronomy was “predominantly practical and utilitarian, directed towards the calendrical, navigational, agricultural, and above all, medical applications of the subject…
anetary models were on the whole considered as fictions devised for predictive purposes.” But, during the course of the sixteenth century “there arose an entirely new kind of princely and

.” By the later decades of the sixteenth century, in these places, as a consequence of astronomers utilizing the patronage system, a fair number of astronomers found themselves dining at princely tables “rather than seated below the salt at university feasts.” Jardine divides the main sites of astronomy into university, court and city, and notes aspects of University such as appointments and curricula as “very often under direct or indirect court control: Wilhelm IV of Hesse-Kassel, for example, closely supervised appointments and the curriculum at his father’s new university of

d conversely, court mathematical appointments were often held concurrently with university posts or filled on university nomination.” Further, Jardine argues that at “least in the court context, the model of stable, salary-based patron-client relationships is inappropriate…
ther, power and dependence arose out of mechanism of mutual recognition of status and honour, regulated by exchange of gifts, tokens, and services.” He notes that in “such an ‘economy of honour’, princes often competed to secure the service of notable astronomers; and they, in turn, played patrons off against each other as they shifted and multiplied their allegiances...

ordspatrons and clients collected and displayed each other. Jardine observes how recent authors have noted ways in which the new cosmologies of the sixteenth century embodied courtly ideals. For example, “in his De rebus coelestibus of 1512 Giovanni Gioviano Pontano, secretary and ambrassador of the Aragonese rulers of Naples, projected into the heavens a court society, in which the planets dance to the tunes of their master, the Sun; much like how that at the

fts were displayed as symbolic representations of power and as object of erudite, often playful conversation- that is, in a somewhat later idiom, as ‘
conversation pieces’.” Often it was through the presentation of instruments, gift-books, and “discoveries in the case of astronomy- that positions of service at court were solicited and secured.” Patronage relationships often helped both parties achieve social distinction, maintaining honor and mutual distinction, even after death; for example:
in 1592 Hieronymus Treutler, Professor of Law at the University of Marburg, delivered a funeral oration for Wilhelm IV of Hesse-Kassel. At the end of the oration Treutler turn dto the Landgraf’s astronomical activities… prais nghim as a skilled practitioner and celebrat nghim as a patron who ha emulated those great examples Julius Ceaser, patron of Sosigene’s reform of the calendar, and Alfonso the Wise.

, “which in accordance with the most exact observations exactly represented the motions not only of the planets, but of the entire firmament”. The Emperor Rudolf heard of the globe and requested that it and its maker be sent to him. “It is wonderful to relate”, declare Treutler, “what pleasure this gave our Prince.” In return, the Emperor sent a personal thank-you letter, received just before the Landgraf’s death.
The Tychonian system
Jardine notes that this “honourable exchange of tokens figures in the oration as the culmination of the Landgraf’s life. Jardine also highlights a dispute between Tycho Brahe and
Ursus where Ursus was accused of stealing a diagram of Tycho’s planetary ordering while at Hven. Tycho eventually brought in the help of Kepler, who wrote a detailed defence of Tycho’s claims to priority Jardine contends that “in the course of these challenges and counter challenges Tycho and Kepler had redefined the object of the dispute in Tycho’s favour…
e claim to priority in the construction of a world system was not the starting point of this courtly duel, but its end-product…
eingso to speak, the final challenge.” Upon recognition of these events, and looking through this interpretation, it seems “the very setting of the world system- a complete physically grounded model of the cosmos—as the goal of astronomy was a product of the competitive practices of courtly exchange of gifts and novelties.” In conclusion, Jardine points that early modern astronomy was formed by its cultural settings, settings in which patronage played a significant part. Further, he suggests that the “courtly patronage of astronomy generated a new agenda for astronomy—specifically, the quest for the true and complete
world system.”
Mario Biagioli
In his book, ''Galileo Courtier: The Practice of Science in the Culture of Absolutism,''
Mario Biagioli looks to shed light on the ways in which a society characterized by patronage relationships affected one of astronomy's, and modern science's, greatest heroes: Galileo Galilei. Biagioli looks to uncover aspects of Galileo's life by “vividly

In a review of Biagioli's work, Larry Wolff noted Biagioli as demonstrating Galileo's legitimacy as a direct consequence of “his ‘career strategies’” and not just “his ‘cognitive attitudes’” and that Galileo is shown to be a master of attaining power and a seventeenth-century career in science The book acknowledges that “gifts within the logic of patronage

n that heneeded to produce or discover things that could be used as gifts for his patrons” Jardine adds, as Biagioli has shown, Galileo's gift to Cosimo II of his discovery of the satellites of Jupiter, transformed into emblems of Medici dynastic power, was a spectacularly successful instance. Through exchange of gifts, highly ritualized and often highly competitive, princes and nobles achieved social distinction, maintaining their honour and mutual recognition.
Robert Westman
Westman has observed “how in the preface to his

in a courtly, or rather curial, humanist language of clerical reform- promoting his new ordering of the planets as a restoration of lost order and harmony, and as a basis for the repair of the derelict calendar.” Westman's “reading is strongly confirmed by the dedication to Paul III of another new ordering of the planetary motions,
Fracastoro’s Homocentrica, in which the strategies of appeal to the humanist Pope are closely similar.”
Richard S. Westfall

Westfall notes that, in the early modern period, the “word 'friend' carries special connotations within a context of patronage; authorities on patronage distinguish what they call instrumental friendship from emotional friendship…
or xampleGalileo's "friends" in Venice appear to have understood that the "friendship" entailed the use of their connections and influence on his behalf. In all of Galileo's attempts to rise up the ladder of Patronage, one of his connections,
Sagredo, would write him words that Westfall considers “
e would be hard pressed to find a better example of the language of patronage.” Westfall writes, “Sagredo, who was clearly tiring of the exercise, wanted to be sure that Galileo understood he had fulfilled his duty as a patron
n riting‘Since I have already satisfied abundantly enough the friendship I hold for you, the obligations to you which I acknowledge, and the favor and help that true gentlemen try to extend to the qualified who deserve it,’ he thought he might now honorably desist.” Westfall also provides fantastic evidence directly from the mouth of Galileo as to the importance of Patronage to himself
and his scientific endeavors:
"Having labored now twenty years, the best ones of my life, in dispensing at retail, as the saying goes, at the demand of everyone, that little talent in my profession that God and my own efforts have given me, my desires would truly be to obtain enough leisure and quiet as would enable me before I die to complete three great works that I have in hand in order to be able to publish them, perhaps with some praise for me and for whoever has helped me in the business. ...

Westfall describes that Galileo, upon discovering Jupiter’s moons, made sure to tantalize the Grand Duke of Tuscany, the position now held by Cosimo of the Medici family, with the honour of being attributed the award of such a discovery by means of them being named after him. As Westfall describes, “Galileo was sure he had found what he wanted, a ticket to

Westfall describes that “

.” Following the discovery of the Jupiter's moons, Galileo would then look to discover their
periods; due to ensuing competition and even some minimizing the importance of only discovering the moons without knowledge of their period, Galileo's “acknowledged position as the messenger from the heavens was threatened”. Westfall also contends that evidence of Galileo's patterns of observing the sky suggest that “at the time Galileo began his
