For mention of the stone with three holes in it, see the write up from Harvard's Peabody Museum here: https://www.peabody.harvard.edu/CMHI/site.php?site=Uxmal
Stephens referred to this area of Uxmal as the "Campo Santo".
The illustration of stone lattice work on the south building of the Nunnery Quadrangle is identical that seen on the west or interior side of the arch at Labna as can be seen here http://www.jayfrogel.com/p247324204/h19abb650#h39d94f4d
Similar lattice work is seen in modern small buildings that the Maya have built.
