Note 227 — No. 81. [Steele and Addison.[225]
Reading edition
Archimedes ordered a sphere included in a cylinder, the diagram of his thirty-second proposition, to be erected upon his tomb. This figure was accordingly carved upon a stone near one of the gates of Syracuse, and became the means of enabling Cicero to discover the sepulchre of Archimedes, covered over with brambles and thorns. (Cicero, "Disp. Tusc.," v. 23.)
