Rachel Feltman: As of late, science and magic are typically regarded as being diametrically opposed: reality versus fiction, motive versus fantasy, trendy sensibilities versus archaic misconceptions. However that hasn’t at all times been the case.
For Scientific American’s Science Shortly, I’m Rachel Feltman. My visitor as we speak is Larisa Grollemond, assistant curator within the Manuscripts Division on the Getty Museum in Los Angeles. She’s behind an exhibit known as Rising Indicators: The Medieval Science of Astrology, which the Getty Heart is presenting till January 5, 2025.

Larisa Grollemond: I’m so comfortable to be right here.
Feltman: So I perceive that you simply curated an exhibit on a extremely fascinating matter on the intersection of historical past, artwork, science, tradition. Would you inform us a bit of bit extra about it?
Grollemond: Certain, the exhibition is known as Rising Indicators: The Medieval Science of Astrology. And what I actually wished to do with this exhibition, as a result of I believe astrology continues to be one thing that’s such a related matter for therefore many individuals—and even more and more so; I believe folks know their solar signal, after all, however additionally they know issues about lunar eclipses and Mercury retrograde. And I really feel prefer it’s a part of our modern visible tradition and our modern tradition in a manner that’s actually built-in with our every day lives.
And for the Center Ages and for folks residing in medieval Europe, astrology was additionally actually part of every day life, and it was utilized in ways in which I believe we might be unfamiliar with as we speak: so by way of making medical choices, nevertheless it—additionally by way of predicting the longer term in sure methods; by way of seeing what you must do each day, on a weekly foundation or a month-to-month foundation; this concept of astrology and particularly the zodiac and the constellations of the zodiac being actually integral to the way in which that folks expertise time as properly. And so interested by it as virtually a timekeeping system in medieval Europe, that was additionally one thing folks had been considering astrologically about.
And so with the exhibition, I actually wished to not simply join the thought of up to date astrological considering or observe to what’s actually an extended legacy of each the visible tradition of the zodiac but additionally the inclusion of astrological considering in type of day-to-day decisionmaking, however, you realize, actually take into consideration the ways in which astrology capabilities in each medieval and modern society.
Feltman: Yeah, that’s tremendous attention-grabbing. I suppose let’s begin with the historic perspective. , if I’m within the medieval period and I’m, like, your common individual, how am I interacting with astrology?
Grollemond: This can be a actually nice query as a result of there’s so many alternative sorts of people who find themselves interacting with astrology within the Center Ages, so there’s actually two facets of this. So we consider astrology as type of a pseudoscience as we speak, I believe. However within the medieval interval, folks had been actually considering of astrology as a part of astronomy. And so we will consider astronomy within the Center Ages because the statement of the heavens, the motion of celestial our bodies, all of those sorts of pursuits—extra scientific pursuits, I might say, we might categorize them as as we speak. Astrology is the interpretation of these actions and the impact of these actions of these celestial our bodies on folks on Earth and on earthly occasions.
So astrology was a part of astronomy, and so it’s an actual science. And so in some methods it’s the purview of very educated folks, of elites, of very literate folks interested by scientific subjects, folks in college settings, folks writing astronomical treatises, folks actually attempting to determine how all of these things works and the ways in which it may be interpreted. And so there’s a complete physique of literature and scientific writing that actually is attempting to clarify what astrology is all about within the Center Ages. And so that’s, I might say, the mental pursuit of astrology.
After which there’s the extra type of every day expertise of astrology and astrological considering. And the books which are on view within the exhibition vary from illuminated manuscripts to printed books of the late fifteenth and early sixteenth centuries, while you actually have an explosion of astrological literature and actually books meant for on a regular basis folks.
So I might say most individuals have a way of the zodiac as extra of a timekeeping system. They could have seen the representations of the indicators of the zodiac on a church portal or on monumental public sculpture not directly. However there are additionally a lot of medieval books that we all know as books of hours or different kinds of devotional books, particularly, that embody zodiac indicators as a part of calendars and the thought of retaining observe of a yr based mostly on the motion of the zodiac. And so there was a way that every zodiacal season, or every astrological season, was a great time for doing sure issues or a nasty time for doing others.
And so medieval astrology is a bit of bit much less of a private pursuit than as we speak, the place we kind of consider it as attempting to determine particular person personalities, compatibility—these actually private types of points. I might say, within the Center Ages, individuals are interested by astrology extra as a seasonal factor.
However actually, towards the top of the Center Ages and particularly within the fifteenth century, astrology is actually certain up with the thought of humoral stability and humoral considering: so the concept the physique has 4 essential fluids in it—that’s black and yellow bile, blood and phlegm—and the astrological signal that you simply’re born underneath influences your private humoral stability, or your type of tendency towards having an excessive amount of blood in your physique or having an excessive amount of black bile in your physique. And that impacts all types of issues: It impacts the way in which that you simply’re handled medically, the potential course of an sickness that you simply may need. It could additionally have an effect on your day-to-day eating regimen. So I’m a Virgo, so I’m a melancholic character, which suggests I’ve an extra of black bile in my physique. And the type of humoral tendency of that’s chilly and dry. And so my eating regimen, I wanna eat heat and moist meals.
And so there’s this actually advanced system that develops towards the top of the Center Ages the place your solar signal, your rising signal, the place of the celestial our bodies at your beginning begins to have an effect on not simply your character however actually the sorts of issues you have to be doing to keep up optimum well being. And so there’s actually an explosion of books and literature within the late fifteenth and early sixteenth centuries that’s actually aiming to provide folks actually sensible recommendation about that. And so if you’re literate, which an growing variety of individuals are towards the top of the Center Ages, you may need entry to one thing like that, which could have a, a sequence of easy woodcuts or kind of easy representations of the indicators of the zodiac and different kinds of issues associated to this concept of the humors and of medical remedy particularly.
So it’s a bit of little bit of an advanced query, like, “How do folks work together with astrological considering within the Center Ages?” as a result of it truly is such a spectrum of individuals actually considering laborious in regards to the science of it after which people who find themselves actually keen on figuring out, “Effectively, what’s the finest time to bloodlet?” Or, “What ought to I be consuming this season?”
Feltman: Yeah, that’s fascinating. And I believe as we speak there’s clearly a extremely big selection of ways in which folks work together with the thought of astrology. I imply, I’m undoubtedly within the camp of, like, you realize, that is mainly simply one other character quiz and nothing extra, however I’ve to confess, I really like silly memes about being an Aquarius, and I pay sufficient consideration to know that the truth that I’m a triple Aquarius is, like—means one thing perhaps not so good [laughs] for individuals who care. However anyway, there are, after all, individuals who interact with it on a a lot deeper stage, too.
I’m curious: When will we begin to see the separation of astrology and astronomy taking place? , the, the historical past of science is stuffed with that type of intersection—we have now alchemy and chemistry pulling other than one another. However when does astrology cease being this mainstream educational pursuit that’s tied up with any research of the celebrities?
Grollemond: I believe that is actually a, a course of that occurs over a number of centuries. So with the growing know-how developed to truly observe the motion of celestial our bodies, to actually, with extra precision, perceive how the Earth strikes across the solar and the way the celebrities transfer, there’s a better understanding of the type of mechanics of astronomy. And as soon as that begins to occur, astrology will get decoupled from astronomy a bit of bit extra. However I might say that that actually takes fairly a very long time to occur. And it’s not likely till the Enlightenment, the seventeenth and 18th centuries, that you simply begin to see an actual type of fissure between astronomy and astrology.
However there are nonetheless very a lot ways in which I believe astronomy is affected by astrology. And it isn’t actually, I might say, till the trendy interval—or one thing, as a medievalist, I might take into account the trendy interval, just like the nineteenth and twentieth centuries—that you simply actually begin to get that full separation of astronomy and astrology.
However they’re so intently associated as pursuits that I might say astrologers as we speak have a extremely intensive understanding of astronomy, and it’s so linked to the thought of statement and of those actually exact astronomical occasions, like eclipses, and type of understanding natal charts all the way down to the minute and issues like that. So I might say as know-how progresses, you’ve a type of a gradual pulling aside of those subjects, however they’re nonetheless so intently associated.
Feltman: Yeah, bringing us into the trendy period, I do know that you simply’re doing a little occasions with distinguished astrologers in relation to the exhibit. So what are you hoping that folks achieve from studying about this connection between astronomy and astrology and historical past?
Grollemond: I at all times assume it’s helpful for modern folks to know not simply that the issues they’re keen on have an extended historical past, as a result of so lots of the issues do, however that is one, I believe, connection level for—virtually about human conduct, like, a really fundamental human conduct: that we want to work out a approach to perceive not simply ourselves however our place within the universe. And the medieval individuals who had been considering astrologically or keen on their zodiac indicators or utilizing astrology to determine what to do daily, I believe that’s such a strong thought as a result of we need to have that connection, I believe, throughout time. And I’m hoping that folks will see themselves in medieval astrology in some methods. And though, I believe, a number of the concepts appear so outdated and kind of humorous in that manner—like the thought of humoral stability and these types of scientific concepts that had been actually informing how folks considered themselves and the way they considered themselves being affected by these cosmic forces that additionally formed the universe—a few of these concepts appear kind of quaint and humorous to us, however they’ve such a logical foundation, and while you begin to kind of perceive the system, you begin to see our modern programs in that.
We’ve got sure patterns of thought and sure, I believe, predilections towards wanting one thing to inform us the solutions that it feels actually common not directly, and so I hope that folks won’t simply perceive that, like, the illustration of the zodiac indicators has this lengthy visible historical past, and there’s an actual kind of, I believe, familiarity with that, and if folks can come to a medieval ebook and perceive, like, “Oh, that’s Taurus,” or, “That’s Virgo,” and there’s nonetheless the symbols that we all know as we speak, that’s a extremely enjoyable, I believe, level of connection. However there’s one thing larger, I believe, in regards to the universality of seeking to the celebrities for solutions that also appears so related and so modern and I believe actually uncovers a bit of little bit of some extent of reference to the Center Ages, which might appear so distant and kind of so distant in our imaginations.
Feltman: Completely. Thanks a lot for becoming a member of us as we speak! This was a extremely attention-grabbing chat.
Grollemond: Thanks a lot. And I, I hope folks come see the present in the event that they’re in LA, and there will likely be a lot on-line to find as properly.
Feltman: That’s all for as we speak’s episode. In the event you’re gonna be across the LA space anytime between now and January 5, undoubtedly take a look at Rising Indicators: The Medieval Science of Astrology. We’ll be again on Friday with a brilliant essential dialog about how weight stigma can impression well being care.
