Plutarch, Crassus
Bernadotte Perrin, Ed.

4. When Cinna and Marius got the upper hand,¹ it was at once apparent that they would re-enter the city not for the good of their country, but for the downright destruction and ruin of the nobles; those who were caught were slain, and among them were the father and brother of Crassus. Crassus himself, being very young, escaped the immediate peril, but perceiving that he was surrounded on all sides by the huntsmen of the tyrants, he took with him three friends and ten servants and fled with exceeding speed into Spain, where he had been before, while his father was praetor there, and had made friends. [2] But finding all men filled with fear and trembling at the cruelty of Marius as though he were close upon them, he had not the courage to present himself to any one. Instead, he plunged into some fields along the sea-shore belonging to Vibius Paciacus. In these there was a spacious cave, where he hid himself. However, since his provisions were now running low, and wishing to sound the man, he sent a slave to Vibius. [3] But Vibius, on hearing the message, was delighted that Crassus had escaped, and after learning the number of his party and the place of their concealment, did not indeed come in person to see them, but brought the overseer of the property near the place, and ordered him to bring a complete meal there every day, put it near the cliff, and then go away without a word; he was not to meddle in the matter nor investigate it, and was threatened with death if he did meddle, and promised his freedom if he co-operated faithfully.

[4] The cave is not far away from the sea, and the cliffs which enclose it leave a small and indistinct path leading inside; but when one has entered, it opens out to a wonderful height, and at the sides has recesses of great circumference opening into one another. There is no lack of water or of light, but a spring of purest flow issues from the base of the cliff, and natural fissures in the rock, where its edges join, admit the light from outside, so that in the day-time the place is bright. The air inside is dry and pure, owing to the thickness of the rock, which deflects all moisture and dripping water into the spring.
