Remembrance of the story of the bull's hide and the foundation of Carthage is preserved in mathematics in connection with the Isoperimetric problem which is sometimes called Dido's Problem (and similarly the Isoperimetric theorem is sometimes called Dido's Theorem). It is sometimes stated in such discussion that Dido caused her thong to be placed as a half circle touching the sea coast at each end (which would add greatly to the area) but the sources mention the thong only and say nothing about the sea.
