Si Monumentum Requires, Circumspice is a 2004 album by the black metal band Deathspell Omega. (The album title is Latin for "If you seek His monument, look around you.")
Musically, it represents a massive departure in sound from the band's previous work, both for the increase in recording quality and for the pursuit of far more avant-garde and experimental directions than the band's previous work. The album is also intentionally structured in the manner of 1970s double albums, with each LP side opening with a "prayer" (side four, which opens with "Carnal Malefactor," being an arguable exception).
"Drink the Devil's Blood" is a re-recording of a track which appeared on the band's first album, Infernal Battles.
