Student Devotion: Answer

 Tomb of Gaspard Monge, after 1818. 
Père Lachaise Cemetery, on the Ronde Point Casimer Perier. 

20th arrondissement. Metro : Père Lachaise or Philippe Auguste

Gaspard Monge (1746–1818), an esteemed mathematician and educator, joined the scientific team that accompanied Napoleon Bonaparte's invasion of Egypt in 1798.  Not only was he a professor of geometry at the École polytechnique, but he was a highly skilled draftsman, and, thus, a much-valued member of the team.

The mausoleum was erected by Monge's students in honor of their teacher; their dedication ("to G. Monge/the students of the École polytechnique") is inscribed on its walls. The mausoleum's design was by Dominique-Vivant Denon, the head of Napoleon's scientific expedition.

Monge's tomb is crowned with an Egyptian-style pylon--a post and lintel gateway topped with a cavetto cornice. The lintel bears Monge's name and an expansive solar disk stretches across the cornice (Anita noted that the sun disk appears to have been recently repaired as two different colors of stone are visible.) A portrait bust occupies the interior.

In  commemoration of the bicentennial of the French Revolution in 1989, Monge's remains were moved to the Pantheon, a burial reserved for notables who have made exceptional contributions to French history and civilization.
