Before the Renaissance, melancholics were portrayed as embodying the vice of acedia, meaning spiritual sloth. The demon of acedia holds an important place in early monastic demonology and proto-psychology. The best-known of the psychological signs of acedia is tedium, boredom or general laziness. In his "Purgatorio" Dante portrayed the penance for acedia as running continuously at top speed. Chaucer's parson includes acedia in his list of vices. "Acedia" in Chaucer's view is thus the enemy of every source and motive for work. Their sixth full-length album "Acedia" was released in November 2009. Acedia is indicated by a range of signs.
