An Alchemist's Kitchen

 

Tesoro del Mondo, "Ars Preparatio Animalium"

Antonio Neri 1598-1600, f. 10r (MS Ferguson 67).

Between 1598 and 1600, Antonio Neri wrote a manuscript filled with alchemical recipes. He entitled it Tesoro del Mondo or "Treasure of the World" and stated that it was a book in draft form, intended for publication. It never did see the ink of a printer's press, but Neri's original did survive intact and today occupies a place of pride in the Ferguson Collection of the University of Glasgow Library. [1]

Tesoro is an ambitious work, devoted to "all of alchemy," containing numerous hand-drawn ink and watercolor illustrations; some of the pictures are allegorical, many others document practitioners working with equipment. Only passing reference is made in this manuscript to Neri's later claim to fame: glass—its most notable appearance in Tesoro  is in illustrations of experimental vessels. 1598 was two or three years before Antonio's glassmaking career is thought to have started. His life was busy on other fronts. He had just been ordained as a Catholic Priest, undergoing the laying on of hands ceremony, probably by his neighbor on Borgo Pinti, the Florentine archbishop Alessandro Ottaviano de' Medici. 1598 was also a year of tragedy for the Neri family; by the summer, his father Neri Neri, personal physician to the grand duke, died of an unknown illness, but not before making arrangements for his family, which included a will. A court magistrate would oversee the now orphaned children's education, inheritance and dowries. They would soon suffer further tragedy in the unexpected death of a brother; sixteen year-old Emilio would leave them on Christmas day of the following year, in Castello outside Florence. 

The losses must have been devastating. In 1598, five of the nine children were still under the age of twenty. Without a mother or father, great responsibility must have fallen on the shoulders of the matriarch of the house, the children's elderly paternal grandmother Maddalena. [2] To outsiders, the Neri's were a wealthy and quite well respected family, but internally, the tragic events undoubtedly threw their lives into turmoil. It is in these circumstances that Antonio started his manuscript. The events allude to the reasoning behind a cryptic Latin quote scribbled at the top of a page above the first recipe of Tesoro: "fuimus troes." It means, "We are Trojans no more" From Virgil's Aeneid, referring to the fall of Troy. [3] 

Early in the manuscript there is a series of four illustrations, each showing a different activity, In order, they are titled The Art of Preparation of Stones, Metals, Plants and Animals. [4] Each is filled with multiple workers engaged in various activities pertinent to the specific art. Each highlights interactions between the Aristotelian elements: air, water, earth and fire. There is no specific indication of where any of the four scenes take place, although some educated guesses can be taken. For instance, the stone workers, or lapidaries, almost certainly are an early incarnation of the famed 'Opificio delle pietre dure' working in the Uffizi's Galleria dei Lavori. But we will leave that discussion for another time. 

Of the four illustrations, "Preparing Animals" focuses on activity within a kitchen. (See above, click to enlarge). The scene is intriguing in that it appears to take place in a domestic setting. Labels call out the four Aristotelian elements; birds hanging from the rafters represent air, fish on a grilling rack represent water, a whole carcass on the spit represents earth and fire appears as itself. The scene suggest that this setting is none other than the Neri family kitchen and that the practitioners of the art are three of Antonio's siblings. In the middle right, a young boy is engaged in turning the spit (in green). The best candidate would be then eleven year-old Allesandro, the eventual heir to the family, whose own son named Neri would carry on the family practice as a physician. Of the two young women pictured, the three family choices are fourteen year-old Lucretia, Sixteen year-old Maria and twenty-six year-old Lessandra.

In one sense, the methodology of alchemy lives-on today in kitchens around the world. The process of combining raw ingredients and cooking them together, of experimentation and of iteratively refining a recipe to perfection, this is not so different from what Antonio Neri and his siblings were doing four hundred years ago.

 (circa 1450 - circa 1512)

Among the ten children born to glassmaker Antonio Neri’s parents, three of them were girls; Lessandra, Maria, and Lucrezia. Because women were not allowed to legally own property, or sign contracts many of the usual sources of information are silent. Most of what we can learn about them is through their relationships with the men around them.

The Neri's were a patrician family, and the children enjoyed a very comfortable existence for the late sixteenth century. There is evidence that all three sisters survived into adulthood. Lessandra was the first-born, nine years older than Maria, and twelve years older than Lucrezia.

When Lessandra was around age seventeen, her famous father, Neri Neri, was appointed as personal physician to the newly crowned Grand Duke Ferdinando de’ Medici. However, only a few short years later their mother Dianora died at age 42, of causes that are unknown, perhaps childbirth. The girls were 22, 13 and 10. A few short years later they lost both their father, and a brother.

Two information sources for the Neri sisters are their birth records kept at the Opera del Duomo and genealogy records for the family which are filed at the National Archives, both in Florence. The baptism records hold a wealth of indirect material through the names of their godparents. While these do not tell us anything specific about them, it does tell us who their influences were; who they looked to for strength and spiritual guidance, under the circumstances, this is the best we can do.

Lessandra (b. 1572) claimed Baccio Valori as her godfather. The Valori family had a long, tragic history with the ruling Medici family. His father, grandfather and great-grandfather were all close Medici supporters, yet each ended up exiled, imprisoned, or executed after relationships soured. On one hand he was faithfully employed by the Medici, yet he reportedly spent a good deal of his time collecting letters and papers documenting his family’s close support of Girolamo Savonarola, the firebrand Dominican priest who lead Florence in the late 1490s, after the Medici had been temporarily expelled from the city.

Lessandra’s godmother was Marietta Gaetani, also from a noble family, which included dukes, cardinals and popes. They played prominent roles in the politics of Pisa, Rome and Naples for several centuries. Marietta’s father owned the house from whose tower Galileo showed the moons of Jupiter to Grand Duke Cosimo II in 1610.

The genealogical records imply that Lessandra later took vows with the S. Agata monastery on the North end of Florence and took the name suor Emilia.

Maria’s (b. 1581) godfather was Monsignor Giovanni Alberti. Giovanni was the son of a Florentine senator. He served as protonotary apostolic for Pope Gregory XIII and as bishop of Cortona under Pope Clement VIII. A godfather serving in the papal inner chambers was a good family contact indeed. Also appearing for Maria was Pierfilippo Perini, a physician and lawyer. The Registri lists Maria Neri's godmother as Alessandra di Girolamo Pepi. Among the prominent Florentine republicans was Alessandra's father, Girolamo. He was tortured by Alessandro de' Medici in the 1530s, upon the family's regaining control of Florence after the siege.The genealogy indicates that she married into the Boscoli family, but further work is needed to identify a specific individual.

Lucrezia (b. 1584), the youngest Neri girl, has a single godparent listed in the register, Montiglio degli Albizi. The Albizi family boasted powerful bankers and politicians. This was another case where deep divisions over Medici rule drove a family apart. Perhaps the best-recognized member of the Albizzi family was Eleonora degli Albizi. She was the young consort of grand duke Cosimo I. Folklore has it that in 1566, Cosimo intended to retire from public life and marry Albizi quietly, after the birth of a girl, but his regent son, Francesco I, forbade it to due to the inheritance complications that would ensue. The story is that Cosimo's long-time personal secretary, Sforza Almeni, leaked word of the clandestine marriage to the family. For his betrayal, an enraged Cosimo murdered Almeni in cold blood. Eleonora later gave birth to Don Giovanni de’ Medici, the uncle and friend of Don Antonio, Neri's sponsor. The specific Albizi family member we are interested in, Lucrezia's godfather, Montiglio degli Albizi, seems to have eluded history. Lucretia married into the Talenti family, but no further details are known.

He entitled it Tesoro del Mondo or "Treasure of the World" and stated that it was a book in draft form, intended for publication. It never did see the ink of a printer's press, but Neri's original did survive intact and today occupies a place of pride in the Ferguson Collection of the University of Glasgow Library. [1]

Tesoro is an ambitious work, devoted to "all of alchemy," containing numerous hand-drawn ink and watercolor illustrations; some of the pictures are allegorical, many others document practitioners working with equipment. Only passing reference is made in this manuscript to Neri's later claim to fame: glass—its most notable appearance in Tesoro  is in illustrations of experimental vessels. 1598 was two or three years before Antonio's glassmaking career is thought to have started. His life was busy on other fronts. He had just been ordained as a Catholic Priest, undergoing the laying on of hands ceremony, probably by his neighbor on Borgo Pinti, the Florentine archbishop Alessandro Ottaviano de' Medici. 1598 was also a year of tragedy for the Neri family; by the summer, his father Neri Neri, personal physician to the grand duke, died of an unknown illness, but not before making arrangements for his family, which included a will. A court magistrate would oversee the now orphaned children's education, inheritance and dowries. They would soon suffer further tragedy in the unexpected death of a brother; sixteen year-old Emilio would leave them on Christmas day of the following year, in Castello outside Florence. 

The losses must have been devastating. In 1598, five of the nine children were still under the age of twenty. Without a mother or father, great responsibility must have fallen on the shoulders of the matriarch of the house, the children's elderly paternal grandmother Maddalena. [2] To outsiders, the Neri's were a wealthy and quite well respected family, but internally, the tragic events undoubtedly threw their lives into turmoil. It is in these circumstances that Antonio started his manuscript. The events allude to the reasoning behind a cryptic Latin quote scribbled at the top of a page above the first recipe of Tesoro: "fuimus troes." It means, "We are Trojans no more" From Virgil's Aeneid, referring to the fall of Troy. [3] 

Early in the manuscript there is a series of four illustrations, each showing a different activity, In order, they are titled The Art of Preparation of Stones, Metals, Plants and Animals. [4] Each is filled with multiple workers engaged in various activities pertinent to the specific art. Each highlights interactions between the Aristotelian elements: air, water, earth and fire. There is no specific indication of where any of the four scenes take place, although some educated guesses can be taken. For instance, the stone workers, or lapidaries, almost certainly are an early incarnation of the famed 'Opificio delle pietre dure' working in the Uffizi's Galleria dei Lavori. But we will leave that discussion for another time. 

Of the four illustrations, "Preparing Animals" focuses on activity within a kitchen. (See above, click to enlarge). The scene is intriguing in that it appears to take place in a domestic setting. Labels call out the four Aristotelian elements; birds hanging from the rafters represent air, fish on a grilling rack represent water, a whole carcass on the spit represents earth and fire appears as itself. The scene suggest that this setting is none other than the Neri family kitchen and that the practitioners of the art are three of Antonio's siblings. In the middle right, a young boy is engaged in turning the spit (in green). The best candidate would be then eleven year-old Allesandro, the eventual heir to the family, whose own son named Neri would carry on the family practice as a physician. Of the two young women pictured, the three family choices are fourteen year-old Lucretia, Sixteen year-old Maria and twenty-six year-old Lessandra.

In one sense, the methodology of alchemy lives-on today in kitchens around the world. The process of combining raw ingredients and cooking them together, of experimentation and of iteratively refining a recipe to perfection, this is not so different from what Antonio Neri and his siblings were doing four hundred years ago.

Sisters of an Alchemist

Portrait of the Egerton Sisters
(no relation to Neri)
English School,  c. 1601-1602

Among the ten children born to glassmaker Antonio Neri’s parents, three of them were girls; Lessandra, Maria, and Lucrezia. Because women were not allowed to legally own property, or sign contracts many of the usual sources of information are silent. Most of what we can learn about them is through their relationships with the men around them.

The Neri's were a patrician family, and the children enjoyed a very comfortable existence for the late sixteenth century. There is evidence that all three sisters survived into adulthood. Lessandra was the first-born, nine years older than Maria, and twelve years older than Lucrezia.

When Lessandra was around age seventeen, her famous father, Neri Neri, was appointed as personal physician to the newly crowned Grand Duke Ferdinando de’ Medici. However, only a few short years later their mother Dianora died at age 42, of causes that are unknown, perhaps childbirth. The girls were 22, 13 and 10. A few short years later they lost both their father, and a brother.

Two information sources for the Neri sisters are their birth records kept at the Opera del Duomo and genealogy records for the family which are filed at the National Archives, both in Florence. The baptism records hold a wealth of indirect material through the names of their godparents. While these do not tell us anything specific about them, it does tell us who their influences were; who they looked to for strength and spiritual guidance, under the circumstances, this is the best we can do.

Lessandra (b. 1572) claimed Baccio Valori as her godfather. The Valori family had a long, tragic history with the ruling Medici family. His father, grandfather and great-grandfather were all close Medici supporters, yet each ended up exiled, imprisoned, or executed after relationships soured. On one hand he was faithfully employed by the Medici, yet he reportedly spent a good deal of his time collecting letters and papers documenting his family’s close support of Girolamo Savonarola, the firebrand Dominican priest who lead Florence in the late 1490s, after the Medici had been temporarily expelled from the city.

Lessandra’s godmother was Marietta Gaetani, also from a noble family, which included dukes, cardinals and popes. They played prominent roles in the politics of Pisa, Rome and Naples for several centuries. Marietta’s father owned the house from whose tower Galileo showed the moons of Jupiter to Grand Duke Cosimo II in 1610.

The genealogical records imply that Lessandra later took vows with the S. Agata monastery on the North end of Florence and took the name suor Emilia.


Maria’s (b. 1581) godfather was Monsignor Giovanni Alberti. Giovanni was the son of a Florentine senator. He served as protonotary apostolic for Pope Gregory XIII and as bishop of Cortona under Pope Clement VIII. A godfather serving in the papal inner chambers was a good family contact indeed. Also appearing for Maria was Pierfilippo Perini, a physician and lawyer. The Registri lists Maria Neri's godmother as Alessandra di Girolamo Pepi. Among the prominent Florentine republicans was Alessandra's father, Girolamo. He was tortured by Alessandro de' Medici in the 1530s, upon the family's regaining control of Florence after the siege.The genealogy indicates that she married into the Boscoli family, but further work is needed to identify a specific individual.

Lucrezia (b. 1584), the youngest Neri girl, has a single godparent listed in the register, Montiglio degli Albizi. The Albizi family boasted powerful bankers and politicians. This was another case where deep divisions over Medici rule drove a family apart. Perhaps the best-recognized member of the Albizzi family was Eleonora degli Albizi. She was the young consort of grand duke Cosimo I. Folklore has it that in 1566, Cosimo intended to retire from public life and marry Albizi quietly, after the birth of a girl, but his regent son, Francesco I, forbade it to due to the inheritance complications that would ensue. The story is that Cosimo's long-time personal secretary, Sforza Almeni, leaked word of the clandestine marriage to the family. For his betrayal, an enraged Cosimo murdered Almeni in cold blood. Eleonora later gave birth to Don Giovanni de’ Medici, the uncle and friend of Don Antonio, Neri's sponsor. The specific Albizi family member we are interested in, Lucrezia's godfather, Montiglio degli Albizi, seems to have eluded history. Lucretia married into the Talenti family, but no further details are known.

Kitchen Alchemy

Tesoro del Mondo, "Ars Preparatio Animalium"

Antonio Neri 1598-1600, f. 10r (MS Ferguson 67).

Between 1598 and 1600, Antonio Neri wrote a manuscript filled with alchemical recipes. He entitled it Tesoro del Mondo or "Treasure of the World" and stated that it was a book in draft form, intended for publication. It never did see the ink of a printer's press, but Neri's original handwritten version did survive intact and today occupies a place of pride in the Ferguson Collection of the University of Glasgow Library. [1]

Tesoro is an ambitious work, devoted to "all of alchemy," containing numerous hand-drawn ink and watercolor illustrations; some of the pictures are allegorical, many others document practitioners working with equipment. Only passing reference is made in this manuscript to glass—its most notable appearance is as experimental vessels. 1598 was two or three years before Antonio's glassmaking career is thought to have started. His life was busy on other fronts. He had just been ordained as a Catholic Priest, undergoing the laying on of hands ceremony, probably by his neighbor on Borgo Pinti, the Florentine archbishop Alessandro Ottaviano de' Medici. 1598 was also a year of tragedy for the Neri family; by the summer, his father Neri Neri, personal physician to the grand duke, died of an unknown illness, but not before making arrangements for his family, which included a will.

The tragic events allude to the reasoning behind a cryptic Latin quote scribbled at the top of a page above the first recipe: "fuimus troes." It means, "We are Trojans no more" From Virgil's Aeneid, referring to the fall of Troy. [3]

It is also remarkable for featuring women at work. Labels call out the four Aristotelian elements; birds hanging from the rafters represent air, fish on a grilling rack represent water, a whole carcass on the spit represents earth and fire appears as itself in several locations. It is not unreasonable to suggest that this setting is none other than the Neri family kitchen and that the practitioners of the art are three of Antonio's siblings.

Of the two young women pictured, the three family choices are fourteen year-old Lucretia, Sixteen year-old Maria and twenty-six year-old Lessandra.

In addition to preparing finished meals, seventeenth century kitchens were busy making more basic ingredients also; preserves, distillations, special salts, herbal extracts and so forth. In addition to foods, medicinal and hygienic products were produced, like syrups and soaps. There is another strong connection between the kitchen and alchemy that lives on today: the methodology of cooking. The process of combining raw ingredients and cooking them together, of experimentation and of iteratively refining a recipe to perfection, this is not so different from what Antonio Neri and his siblings were doing four hundred years ago.
