A peculiar phrase
In the Russian regional press writing about shungite, you keep finding the rock referred to in passing as "
заветный камень царей", a phrase that translates to something like "the cherished stone of tsars" or "the secret stone of tsars". The page at zaonego.ru, a Karelian regional site, uses this framing in the title of one of its main pieces on the rock. The phrase carries weight in Russian:
заветный is not a casual word. It implies something held close, something inherited, something passed across generations as a private treasure.
The phrase makes a claim. The claim is that shungite is not a rock that the Russian tsars happened to encounter. It is a rock that mattered to them, personally, across more than one reign, in a documented and traceable way.
That claim is, on inspection, defensible. Three Russian rulers across more than a century each had a documented, personal, repeated relationship with the rock. Their reigns chain together. Each left a mark on the next. The rock sits at the centre of a small but real Romanov-dynasty pattern.
Marfa Romanova, 1601-1606
The first ruler in the chain is not technically a tsar but the mother of one. Ksenia Ivanovna Shestova, exiled to Tolvuya by Boris Godunov in 1601, tonsured as the nun Marfa, drinks daily from a spring that flows through the local black slate (the rock that two and a half centuries later would be named shungite). Her epileptic seizures stop. When her son Mikhail Romanov is acclaimed the first Romanov tsar in 1613, ending Russia's Time of Troubles, the spring is renamed
Царицын ключ (the Tsaritsa's Spring) in her honour. Tolvuya receives privileges by her decree.
This is documented in regional sources going back to N. S. Shaizhin's 1911-1912
Заонежская заточница (covered in a separate thread), and the spring itself remains a pilgrimage site to the present day. In July 2013 a chapel was built over it, dedicated to the Royal Passion-Bearers (the canonised last imperial family).
The pattern starts here. The rock heals the matriarch of the dynasty. The dynasty remembers the spring.
Peter the Great, 1714-1724
A century after Marfa's exile, in 1714, a worker at Peter the Great's new copper-smelting operation in Karelia falls seriously ill. He encounters the same spring, by then overgrown but still flowing. After three days he is back at work.
When Peter is told the story, he does not treat it as a curiosity. He sends his court physicians (Robert Areskine and Laurentius Blumentrost) to test the water chemically. On the basis of their report, on 20 March 1719, Peter founds
Марциальные воды (Marcial Waters) by personal decree. The decree text is preserved in the
Полное собрание законов Российской империи (Complete Collection of Laws of the Russian Empire), volume 5, no. 3338. It is the founding charter of the first state-sponsored spa in Russian history.
Peter then visits the spa himself. Not once. Russian historical records document his visits in
1719, 1720, 1722, and 1724. Four visits in the last five years of his life. He took his wife, the future Empress Catherine I. He took members of his court. The Marfa-spring complex was, by this point, under direct imperial patronage, and the patron was the most powerful Russian ruler since Ivan the Terrible.
Russian regional sources also report that Peter ordered the spring water itself transported to Saint Petersburg for his use between visits. The phrasing in
med.wikireading.ru's history of the discovery: "
Petr discovered the spring's reputation and ordered shungite water shipped to St. Petersburg." Shungite-filtered water was, in other words, treated as a working palace medicament.
The 1714-1724 decade is when the dynasty's relationship with the rock becomes institutional rather than family-private. The grandson of the woman whose body recovered at the spring builds the spa over it.
Across the rest of the Romanov reigns
The chain does not end with Peter. Marcial Waters continued to operate as an imperial-period spa under successive reigns. The 200th anniversary of the spa's founding was marked in 1919, with documentation produced by Imperial-period historians like Shaizhin even amid the upheaval of that year. The 300th anniversary was celebrated in 2019, with the modern Russian medical-history literature, including PMID 31513172 (Aleksandrov 2019, "
300 лет первому российскому курорту: история изучения Марциальных вод"), reviewing three centuries of work on the place.
That Aleksandrov 2019 paper is itself worth pausing over. Its title says
"300 years of the first Russian resort: history of the study of Marcial Waters". Three hundred years of physicians, balneologists, geologists, and historians writing about a spa whose water flows through a layer of shungite.
The phrase, decoded
Заветный камень царей in this light is not poetic flourish. It is a description of a rock that:
- Healed the mother of the founder of the Romanov dynasty
- Was recognised in the dynasty's family memory across at least one century before being institutionally adopted
- Was the active medicinal water-source on which the first state-sponsored Russian spa was founded by personal decree of Peter the Great
- Was personally consumed (in the form of spring water filtered through the rock) by Peter the Great repeatedly across his last decade
- Was transported under imperial logistics to the imperial capital
- Continued to anchor a state-supported balneological tradition for the entire 200-year span of subsequent Romanov rule
- Has had its medical-historical literature continuously updated for 300 years
The rock has, in regional Russian framing, an imperial pedigree. The pedigree is documented across multiple historical sources, the spring itself still flows, and the spa still operates.
The "
secret stone of tsars" framing is, as far as regional Russian shungite literature goes, justified by the documented history. It is one of the few stones on Earth with a continuous traceable connection to a specific ruling dynasty across more than three hundred years.
Where the trail leads
The deeper documentation lives in:
-
Полное собрание законов Российской империи vol. 5 no. 3338 (1719), the founding decree itself, available in the imperial-law collections held by Russian state archives
-
Shaizhin NS 1911-1912 Заонежская заточница, the early-20th-c. anchoring monograph (covered in separate thread)
-
Aleksandrov VV 2019, "300 лет первому российскому курорту", PMID 31513172, the modern medical-history review
-
Russian Presidential Library "Marcial Waters" dossier, prlib.ru holds Petrine-era charter copies and related Imperial-period material
-
Robert Areskine and Laurentius Blumentrost biographical sources, both physicians have surviving Russian, British (Areskine was Scottish-born, Robert Erskine), and German (Blumentrost was German-born) archival material on their Petrine service
-
The Marfa Romanova spring chapel at Tolvuya (built 2013), the modern pilgrimage site dedicated to the Royal Passion-Bearers, currently administered by the Petrozavodsk Diocese
The rock, the spring, the spa, the Romanov dynasty, the imperial physicians, the founding decree, the surviving chapel, the 300-year continuous medical-history literature: all of these are accessible. The phrase "
заветный камень царей" is not a flourish. It is a label for a documented continuous tradition.
