Si monvmentvm reqvires, circvmspice is the third full-length album by black metal band Deathspell Omega. The album title is a grammatically mis-quoted version of the Latin epitaph on the tomb of Christopher Wren in St Paul's Cathedral (built by him), meaning "If you seek his monument, look around you". This album is the first part in a trilogy of albums released by the band, followed by Fas – Ite, Maledicti, in Ignem Aeternum in 2007 and Paracletus in 2010. The trilogy has been described as "a theological dispute on the divine essence of the Devil, the roles and virtues of faith and the place of man therein", particularly from a Theistic Satanist perspective. One interpretation of the purpose of the album is to examine and proclaim that "Satan is pervading every part of our material and metaphysical realms and how Man’s relationship with Him should be one of reverence and devotion." The album draws on themes of putrefaction, decomposition, antinatalism, as well as the work of the French philosopher Georges Bataille.
