Italian black metal band Canticum Diaboli have detailed their upcoming full-length album, Compendium Horribilis, arriving November 11th, 2026, via Ad Noctem Records across CD and digital formats.

Formed in 2014 by guitarists Apostata and Laevus, the group followed their debut De Flammis et Dei Ruina and 2023 EP Ecce Pontifex Bonifatio with eight tracks centered on Italian history, folklore, and superstition. Narrative subjects across the record range from the 1527 Sack of Rome and the execution of Giordano Bruno to Venetian vampire lore and the Monster of Ravenna.

The album pairs tremolo guitar lines with blast-beat percussion influenced by Swedish black metal predecessors such as Watain, Dark Funeral, and Necrophobic, delivered alongside lyrics in Italian and Latin. Recording sessions took place at New Sin Studio utilizing analog tracking equipment to capture an organic performance sound.

Guitarist Apostata designed the visual presentation, utilizing 16th-century printmaking techniques for the cover artwork featuring the Monster of Ravenna.

Compendium Horribilis is scheduled for release on November 11th, 2026, via Ad Noctem Records.
