With Irony About the Author

More than a quarter of a century ago, I asked myself the question: why do penguins and people waddle?

I studied the locomotion of people and animals, movement of machines, observed in zoos and museums, studied the structure of birds and human, experimented and analyzed, developed a mathematical apparatus. For the penguins the operation was developed: circular periacetabular osteotomy of the pelvis with rotational transposition of the proximal area of attachment of the ligament of the head of femur (ligamentum capitis femoris, ligamentum teres). A similar operation can improve the gait of some people too.

In the beginning, there was a question...

Joubert J, painting – Jacob's struggle with God in the form of an angel (17-18th cent.). Depicting the circumstances and mechanism of the ligamentum capitis femoris (LCF) injury based on the description in the Book of Genesis: 25 And Ja cob was left alone; and there wrestled a man with him until the breaking of the day. 26 And when he saw that he could not pre vail against him, he struck against the hollow of his thigh ; and the hollow of Jacob's thigh was put out of joint, as he was wrestling with him. … 33 Therefore do the children of Israel not eat the sinew which shrank, which is upon the hollow of the thigh, unto this day; because he struck against the hollow of Jacob's thigh on the sinew that shrank. ( 1922LeeserI , Genesis (Bereshit) 32:25-26,33) More about the plot in our work: Ninth month, eleventh day ( 2024АрхиповСВ. Девятый месяц, одиннадцатый день ).

Dating and authorship of the Book of Genesis

An original perspective on the dating and authorship of the Book of Genesis. This approach can reconcile all faiths, including atheists and scientists. English version of the article: https://roundligament.blogspot.com/2026/02/great-compilation-introduction.html Abstract The Book of Genesis (Bereshith) was composed in Egypt during the 17th century BCE and reached its definitive protographic form following the Minoan eruption of Thera. This study argues that the work was the result of a collaboration between an Egyptian polymath and a distinguished scribe of Asiatic descent. By analyzing ancient texts, anatomical descriptions, archaeological data, Bronze Age cultural history, and climatic markers, this article demonstrates that the book emerged from the work of a high-ranking socio-political committee within the Egyptian House of Life. We argue that the inclusion of precise anatomical data, such as the ligamentum capitis femoris, serves as a diagnostic marker of this Egypti...

MYTHS AND MISCONCEPTIONS

MYTHS AND MISCONCEPTIONS ( Erroneous and folkloric beliefs, folk and traditional stories...) LCF in English Bibles The first written mention of the LCF in humans is found in the ancient Hebrew book – Bereshit (Genesis). In English translations of the Bible, LCF is denoted by various terms, often not explicitly referring to the «ligament». The Shortest Comments on Genesis, Chap. XXXII-XXXIII In the selected excerpt, the symptoms, mechanism, and differential diagnostic test for the injury to LCF are provided, along with details about the circumstances, time, and place of the biblical trauma. 1609-1583bcProtoBereshit Hypothesis: in the work of fiction, an unknown physician-encyclopedist for the first time pointed out damage to the LCF as a cause of gait disturbance. 922-722bcElohist A variant of the oldest description of damage to the LCF and the cause of lameness in Hebrew, dating from 922-722 BC. 8cent.bcHomer The...

Human Children. Retelling of Chapter 5

Short retelling of chapter 5 of the essay: Arkhipov S.V. Human Children: The Origins of Biblical Legends from a Physician's Perspective. Joensuu: Author's Edition, 2025. [In Russian] Chapter 5. ADAM AND EVE The Book of Genesis narrates the story of a tribe founded by Adam and Eve, described as the "mother of all living." From a genetic perspective, they are depicted as siblings, with an age difference of 18–25 years. According to the biblical epic, they formed humanity’s first family, sustaining themselves on pre-existing fruits and seeds. Their initial home was the "garden in Eden," located "in the east" relative to the narrator. The text identifies geographic markers for Eden’s location: lands like "Asshur," "Cush," and "Havilah," and rivers named "Pishon," "Gihon," "Hiddekel," and "Phrath." The narrator also notes the region’s economic value, mentioning "gold," ...

The First Conservative Treatment

Conservative treatment of ligamentum capitis femoris (LCF) pathology is, without exaggeration, a highly complex subject. We understand how to repair LCF surgically, although we have not yet achieved significant success in this (2024). Methods of drug therapy for changes in LCF are not even discussed today. The first attempt at treating post-traumatic changes in LCF with recurrent hip dislocations was made by Galen of Pergamon (129-210/217 AD) over 19 centuries ago. In Hippocratis de articulis liber et Galeni in eum commentarius quatus (IV, 40) , he wrote: « And when mucus builds up in the joint, then the ligament [LCF] softens and weakens as a result. And it does not matter whether you call it a ligament ( σύνδεσμον ) or a connecting sinew ( νεῦρον συνδετικόν ). For those ligaments that have a rounded shape like tendons are usually called connecting sinews by anatomists. And we have already cured this kind of hip dislocation twice, and it did not dislocate again. Drying medica...

Tiktaalik roseae

TIKTAALIK ROSEAE The first truly tetrapod animal (Limbed tetrapods) is recognized as the lobe-finned fish Tiktaalik roseae (clade Elpistostegalia), discovered in rocks aged about 375 Ma (2006DaeschlerEB_JenkinsJrFA; 2008ShubinN; 2017ShubinN). Discoveries in recent years have allowed us to place the taxa of early tetrapodomorphs in the following order: Tinirau, Eusthenopteron, Megalichthys, Panderichthys, Qikiqtania, Tiktaalik, Elpistostege, Parmastega, Ventastega, Acanthostega, Elginerpeton, Ymeria, Ichthyostega (2022StewartTA_ShubinNH). The closest ancestor of Tiktaalik roseae, the fragments of the skeleton of which are relatively well preserved, is Panderichthys. Reconstruction of the prehistoric fish Pandericthys Author Tyler Rhodes; original in the wikipedia.org collection (license CC BY-SA 3.0, no changes).

Human Children. Retelling of Chapter 7

Short retelling of chapter 7 of the essay: Arkhipov S.V. Human Children: The Origins of Biblical Legends from a Physician's Perspective. Joensuu: Author's Edition, 2025. [In Russian] Chapter 7. ABEL AND CAIN A pivotal moment in the saga of early humanity was the departure from the "Garden of Eden" to cultivate fields, with a focus on growing grains, as "bread" is mentioned earlier in Genesis. The text does not specify where Adam and Eve settled after leaving Eden, but we can infer it was a warm region with ample water for crops and livestock. This is evidenced by their sons’ occupations: Cain as a "tiller of the ground" and Abel as a "keeper of sheep." Over time, Cain and his family moved "east of Eden" to the land of "Nod," where he founded a "city"—a settlement with permanent dwellings. His descendants developed sophisticated skills: some mastered music, playing the stringed "lyre" and the ...
