Appian of Alexandria Civil Wars 4.17.136

[136] Rhascus, the Thracian, brought many troops from the mountains. He asked and received as his reward the pardon of his brother, Rhascupolis, from which it was made plain that from the beginning these Thracians had not been at variance with each other, but that seeing two great and hostile armies coming into conflict near their territory, they took sides in the contest in such a way that the victor might save the vanquished. Portia, the wife of Brutus and sister of the younger Cato, when she learned that both had died in the manner described, although very strictly watched by domestics, seized some coals of fire that they were carrying, and swallowed them. ¹ Of the members of the nobility who escaped to Thasos some took ship from thence, others committed themselves with the remains of the army to the judgment of Messala Corvinus and Lucius Bibulus, men of equal rank, to do for all what they should decide to do for themselves. These came to an arrangement with Antony and Octavius, whereby they delivered to Antony on his arrival at Thasos the money and arms, besides abundant supplies and a great quantity of war material, there in store.
