Looking at old stuff from the 1500s has shown us some cool things about a special lab where an alchemist worked during the Renaissance.
By studying old things from the 1500s, we've learned some cool stuff about a special lab where a scientist from that time mixed chemicals to try and make new things.
This castle was once home to a famous Danish astronomer named Tycho Brahe. He also liked alchemy, so he built a really cool lab in the castle to do experiments.
After Brahe passed away, the king ordered the castle to be torn down. Today, only a few pieces remain from his alchemy lab, including these five fragments.
In a new study, a scientist named Kaare Lund Rasmussen, who is an expert in analyzing old things, used special techniques to study the pieces found from the castle's lab. He wanted to discover more about how the lab was used and what kind of experiments were done there.
Alchemists during Brahe's time were known for their secrecy. They rarely shared their knowledge or discoveries with others. This makes it difficult to understand exactly what Brahe was doing in his laboratory. We know he was both an astronomer and an alchemist, but the specifics of his alchemical work remain shrouded in mystery. This lack of information makes the discovery of these shards even more intriguing, as they offer a rare glimpse into the secretive world of Renaissance alchemy.
While Brahe was known for his alchemy, only a few of his recipes have been preserved. Based on the existing information, it seems that Brahe belonged to a group of alchemists who focused on creating medicines to cure diseases prevalent during their time, such as plague, syphilis, and leprosy. This sets him apart from other alchemists who were more interested in transforming common metals into gold. Brahe's dedication to medicinal alchemy highlights his interest in improving human health and well-being through scientific exploration.
"It might seem odd that Tycho Brahe was involved in both astronomy and alchemy," said Poul Grinder-Hansen, a curator at the National Museum of Denmark, "but when you understand his perspective on the world, it starts to make sense." This statement suggests that Brahe's interest in both astronomy and alchemy was not contradictory, but rather reflected a holistic approach to understanding the universe, where the celestial and terrestrial realms were interconnected.
Grinder-Hansen, who co-authored the study, further explained Brahe's worldview, saying, "He believed there were clear connections between the celestial bodies, earthly substances, and the human body." This perspective helps us understand why Brahe pursued both astronomy and alchemy, as he saw them as interconnected parts of a larger whole.
The chemical analysis of the shards aimed to identify any traces of substances that the original glass and ceramic containers had come into contact with. This analysis revealed significant levels of nine trace elements on either the inner or outer surfaces of the shards, including nickel, copper, zinc, tin, antimony, tungsten, gold, mercury, and lead. These elements provide clues about the types of substances Brahe was working with in his alchemical laboratory and the processes he was using.
Four of the detected elements—copper, antimony, gold, and mercury—are known ingredients in Brahe's three surviving medicinal recipes. This suggests that these preparations could have been made in the alchemical laboratory at Uraniborg. However, the study authors cautioned that the presence of these elements doesn't definitively prove that they were used for making Brahe's medicines. Other alchemical processes or experiments could also have involved these elements.
The remaining five elements detected in the analysis were not mentioned in Brahe's surviving recipes. This suggests that they could be remnants from other alchemical experiments, the nature of which remains unknown. These unidentified experiments add another layer of mystery to Brahe's alchemical work and raise questions about the full extent of his scientific pursuits.
Rasmussen further elaborated on the significance of the unidentified elements, stating that Brahe himself had expressed strong opposition to the pursuit of turning base metals into gold, considering it a waste of both time and resources. This suggests that the five elements not found in Brahe's medicinal recipes were likely involved in other, now unknown, attempts at creating medicines. Rasmussen emphasized the excitement surrounding this discovery, stating, "This is really exciting, because this is the very first glimpse we get of what really happened in the alchemy lab on Ven." These findings offer a unique opportunity to delve deeper into the mysteries of Brahe's alchemical pursuits and shed light on the unexplored facets of his scientific work.
Most of the elements found in significant quantities on the shards are not particularly surprising given their historical context. For example, gold and mercury were commonly used in medicinal treatments during that era, particularly among the wealthy.
However, the presence of tungsten is quite perplexing. Rasmussen explained, "Tungsten had not even been described at that time, so what should we infer from its presence on a shard from Tycho Brahe's alchemy workshop?"
The researchers propose a few possibilities for the tungsten's presence. One explanation is that a mineral containing tungsten might have been processed in the Uraniborg lab, inadvertently separating the tungsten without Brahe's knowledge.
Another intriguing possibility is that Brahe might have been aware of tungsten's existence, though not by that name. In the early 1500s, a German mineralogist named Georgius Agricola noted an unusual substance in tin ore, which he called "Wolfram," meaning "wolf's froth." This substance was later renamed tungsten. This suggests that knowledge of tungsten, or at least its precursor in ore form, existed during Brahe's time, and he may have been experimenting with it.
These findings open up exciting avenues for further research into the history of science and the practices of Renaissance alchemists. It seems there is still much to discover about Brahe's alchemical work and the potential knowledge he possessed.
Rasmussen acknowledged the possibility that Brahe might have been aware of tungsten's existence through Agricola's work, stating, "Maybe Tycho Brahe had heard about this and thus knew of tungsten's existence." However, he emphasized that this is merely a theoretical explanation and cannot be confirmed based on the current analysis. The presence of tungsten remains a tantalizing mystery, hinting at the possibility of Brahe's knowledge extending beyond what was formally documented during his time. It underscores the importance of further research to uncover the full extent of his scientific pursuits and the hidden knowledge of Renaissance alchemists.
