1586PiccolominiA

Fragments from the book Piccolomini A. Anatomicae praelectiones (1586). One of the first discussions of the biomechanics of the ligamentum capitis femoris (LCF) with a description of its shape, mechanical properties and attachment.

Quote p. 378-379.

[Lat]

De femoribus.

Hoc rotundum & magnum femoris caput, intruditur in magnum coxendicis acetabulum; a cuius medio emergit vinculum teres ac validissimum, femur cum coxendice copulans, & hanc articulationem firmissimam stabiliensis.

…

Cur ex animalibus progressiuis, alia recta, alia prona incedunt progredumtutue? Hanc varietatem efficit vatra ligamenti rotundi ac validi e capite femoris in acetabulum inserto. Nam si inserutur versus superiotem acetabuli partem, recta progrediuntur animantia, vt homo, si versus lateralem, prona incedunt, vt bos, equus. Qud sit, vt ille faciem celsam sit sortitus caelum suspicientem, menti commodiu sinseruientem; haec vero deptessam, terram despicientem, a qua dumtaxat corporis alimenta capessaant.

Translation

[Eng]

On the thigh bones.

This round and large head of the femur is inserted into the large acetabulum of the pelvis; from its middle comes a round and very strong ligament that connects the femur to the pelvis, which makes this joint very stable.

…

Why among walking animals do some move upright and others obliquely? This difference arises from the tension of a round and strong ligament inserted from the head of the thigh bone into the acetabulum. For if it is attached to the upper part of the acetabulum, animals walk upright, like a man; if to the side, they move obliquely, like a cow or a horse. As a result of this, those [animals] whose face is raised up and directed towards the sky are better adapted to mental actions than those whose face is lowered, turned towards the earth, from which alone they receive food for the body.

The Solar System

The Solar System As a result of a mysterious catastrophic event about 13.8 billion years ago, the Universe was formed (2012HawkingS; 2020AghanimN_RoudierG). In it, giant cloud-like accumulations of plasma, molecules and dust became the points of star formation (2011MurrayN). A series of their generations, igniting, functioning and collapsing, led to the appearance of various chemical elements through staged reactions of nuclear fusion (1998IshkhanovBS_TutynIA). The Sun was born for at least ten million years by compressing a concentration of molecular gas and parts of the most ancient stars (2010HanslmeierA). As a result, 4.5682-4.567 billion years ago, the Solar System self-organized, at the dawn of its life consisting of a central luminary and a protoplanetary gas and dust disk (2013HazenRM). At least the oldest meteorite inclusions were fused 4.568-4.565 billion years ago, and at most three million years later, accretion of chondrite globules occurred (1995AllègreCJ_GöpelC). T...
