Ciacco

Ciacco is presented in surviving sources as a named soul introduced by Dante in Inferno, Canto VI, placed in the third circle of Hell reserved for the sin of gluttony. The name itself is treated in commentary and later literature as a nickname with porcine/gluttonous connotations — an early commentator summarized the name as 'a pig's name' applied for his gluttony — but the sources note uncertainty about the name's existence in literature before Dante. Dante's poem supplies the original literary appearance; Boccaccio later reuses the figure in the Decameron, where Ciacco functions as a familiar type of extreme gourmand.

Dante's text gives no detailed physical description of Ciacco beyond his status as one of the damned in the third circle of Hell (Inferno, Canto VI). In the poem he appears as a tormented soul who can converse with the pilgrim Dante; later dramatic and printed editions cast the role in performances, but the primary literary evidence lacks distinctive bodily, clothing, or visual particulars beyond his placement among the gluttons.

Within Dante's narrative Ciacco speaks to Dante and, as part of the poem's device, delivers a prophecy concerning factional conflict in Florence (Inf. 6.64–72). Sources characterize him behaviorally as emblematic of extreme gluttony (Boccaccio calls him 'the most gluttonous fellow that ever lived'). The available materials do not ascribe independent supernatural powers to Ciacco beyond his role as a speaking damned soul in the allegorical afterlife; prophetic speech in the poem functions as a literary device rather than documented magical capacity.
