Anatomists’ errors

Those who attempted to write about the human body after Galen consider a certain structure in the base of the heart to be a bone [os cordis], and compare it to the one placed before the top of the larynx (fig. 1 and 2, chapter 13), called u(oeidh/j, hyoid, from the u shape. Nor did it suffice those people so to invent a bone in the base of the heart: worse yet, they added that the base of the heart, and therefore even the entire heart, is braced by it no differently than the base of the tongue is braced by that bone [os hyoideum] which is placed before the larynx. For they believe that the heart is braced and moved by such a bone, without even considering whether a heart possessed of such a bone could be propped up by it just as an iron rod would support a bed in the air: no sooner would it be attached to the bed than both would fall down. At the same time, we cannot deny that the connection of the four vessels of the heart to their adjacent surfaces does somewhat support the heart.
