Archimedes' ''[[Book of Lemmas]]'' or ''Liber Assumptorum'' is a treatise with 15 propositions on the nature of circles. The earliest known copy of the text is in [[Arabic language|Arabic]]. [[T. L. Heath]] and [[Marshall Clagett]] argued that it cannot have been written by Archimedes in its current form,{{cn|date=April 2025}} since it quotes Archimedes, suggesting modification by another author. The ''Lemmas'' may be based on an earlier work by Archimedes that is now lost.{{cn|date=April 2025}}

Other questionable attributions to Archimedes' work include the Latin poem ''[[Carmen de ponderibus et mensuris]]'' (4th or 5th century), which describes the use of a [[hydrostatic equilibrium|hydrostatic balance]], to solve the problem of the crown, and the 12th-century text ''[[Mappae clavicula]]'', which contains instructions on how to perform [[assay]]ing of metals by calculating their specific gravities.<ref name="kingcrown">[[Oswald A.
