Granius Licinianus35.20; there is some uncertainty as to which Marius this was. He was probably not the son of Gaius Marius, who seems to have been with his father at the time.
Orosius 5.21.7 (Latin text): "Marcus Marius was dragged from a goat-pen and bound on orders of Sulla; after he was led across the Tiber to the tomb of the Lutatii, his eyes were gouged out, his body parts were cut off bit by bit or even broken, and he was slaughtered". Livy's account survives only in Periocha 88: "Sulla polluted (inquinavit) a most glorious victory by cruelty such as no man had ever shown before. He slaughtered 8,000 men, who had surrendered, in the Villa Publica; ...and had Marius, a man of senatorial rank, killed after having his legs and arms broken, his ears cut off and his eyes gouged out".
Evidence of the marriage from a fragment from Sallust's Historiae (1.37, with the commentary on the passage by P. McGushin, Sallust: the Histories, 1992); Syme, Ronald (1964), Sallust, University of California Press, pp. 85–86, ISBN978-0-520-92910-4: if they were married, "it can be taken that Catilina promptly discarded her". The existence of a marriage between Gratidianus' sister and Catiline is a subject of debate and often doubted.

The ancient sources can be oblique; for instance, Seneca, De clementia 1.11.2, refers to "Perugian altars" in listing evidence for the harshness of Augustus in youth, tempered by age, without explanation. In Spectacles of Death in Ancient Rome (Routledge, 1998, 2001), Donald G. Kyle reviews this and related incidents and points out that 300 is a "conventional number" (p. 58 online).

Presumably bound to a stake, given his broken limbs; implied also by Lucan's use of the verb pendet, "hang suspended", Bellum civile 2.176. The traditional punishment for perduellio, the charge for which Gratidianus probably prosecuted the elder Catulus, was death by scourging. The convicted man was tied to a furca or palus, originally a dead tree, arbor infelix. Those bound to an arbor infelix were considered consecrated to the chthonic gods; see Anne Weis, "The Motif of the adligatus and Tree", American Journal of Archaeology 86 (1982), p. 27. Catulus had preferred suicide to this fate, the threat of which may have shaped his son's revenge. There are also a few indications that crucifixion might have been used, contrary to custom, on citizens during the civil war. See Rawson, "Sallust on the Eighties?", pp. 175–176, and discussion at Q. Valerius Soranus: Execution. The word stanti has been emended in some editions to spiranti, parallel with Cicero's phrase plenum animae et spiritus, so that the passage means Gratidianus was still "alive and breathing" when his head was lopped off; see Damon, "Com. Pet. 10", passim.
Cassius Dio 43.24 is the unique source for the incident.
Suetonius, Life of Augustus15, attributing multiple but unnamed sources: "Certain sources write that three hundred men of both orders were chosen from those who surrendered, and slaughtered in the manner of sacrificial victims (more hostiarum) at the altar built for the Divine Julius on the Ides of March".
Cassius Dio48.14.2.: "And the story goes that they did not merely suffer death in an ordinary form, but were led to the altar consecrated to the former Caesar and were there sacrificed".
