Julius Caesar

Julius Caesar – Crosses the Rubicon, 49 BC
Coming up with his troops on the banks of the Rubicon, which was the frontier of his province, he halted for a while, and revolving in his mind the importance of the step he meditated, he turned to those about him, saying: ‘Still we can retreat! But once let us pass this little bridge, – and nothing is left but to fight it out with arms!’

Even as he hesitated this incident occurred. A man of strikingly noble mien and graceful aspect appeared close at hand, and played upon a pipe. To hear him not merely some shepherds, but soldiers too came flocking from their posts, and amongst them some trumpeters. He snatched a trumpet from one of them and ran to the river with it; then sounding the “Advance!” with a piercing blast he crossed to the other side. At this Caesar cried out, ‘Let us go where the omens of the Gods and the crimes of our enemies summon us! THE DIE IS NOW CAST!’

Accordingly he marched his army over the river; [then] he showed them the tribunes of the Plebs, who on being driven from Rome had come to meet him, and in the presence of that assembly, called on the troops to pledge him their fidelity; tears springing to his eyes [as he spoke] and his garments rent from his bosom.

My question is who is that mysterious piper? If you see all great people history there was always someone who gave a little nudge for them to become great. Magical piper?
