Buoyancy tersely: Buoyancy = weight of displaced fluid. Archimedes' principle does not consider the surface tension (capillarity) acting on the body, but this additional force modifies only the amount of fluid displaced and the spatial distribution of the displacement, so the principle that "Buoyancy = weight of displaced fluid" remains valid. The weight of the displaced fluid is directly proportional to the volume of the displaced fluid (if the surrounding fluid is of uniform density). In simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or
Legend of the Four Blood Bars warned about having found the legend ""according to what I found written"" in a supposed ""personal manuscript"". Even though one cannot impute the invention of the legend to Beuter with absolute security, it seems clear that the resource of the supposed ""personal manuscript"" either refers to a previous source or was subterfuged to avoid any subsequent criticism. Historian points out that, in any case, whether he was the inventor of Beuter's legend or if the legend is an adaptation of an earlier version that circulated in , the ""personal manuscript"" would not be much prior to 1551.
