I saw this on the wiki page for Vergil and found it fascinating:
Etymological fancy has noted that his cognomen MARO shares its letters anagrammatically with the twin themes of his epic: AMOR (love) and ROMA (Rome).
I think that’s awesome. Vergil doubtlessly was aware of this.
Hello, Luce!
When I got tired writing down notes from my teachers during this scholar year, I used to draw the next square (imagine that it´s a 4x4 matrix) and then I tried to find out any sort of relationship in these letters and how it was possible…:
M-----A-----R-----O
A-----M-----O-----R
R-----O-----M-----A
O-----R-----A-----M
It´s something curious. Do you know about the engraving of the great Dürer whose name is Melencolia I? I attended to an exposition about Dürer here in Madrid some time ago. I get fascinated trying to establish the connection between the disposition of the numbers and the numbers themselves by means of linking them with lines.

NEC MORA 
I like this one:
primusab aetherio uenit Saturnus Olympo
armaIouis fugiens et regnis exsul ademptis.
is genus indocile ac dispersum montibus altis
composuit legesque dedit, Latiumque uocari
maluit, his quoniam latuisset tutus in oris
LATIVM - MALVUIT
This wordplay was curiously preserved in a recently published verse translation.
Perhaps Vergil and Durer were sort of the grandfathers of sudoku?
