Theseus

And dividing themselves into two bands, one of these marched openly against the city from Sphettus with their father; the other hid themselves at Gargettus and lay in ambush there, intending to attack their enemies from two sides. But there was a herald with them, a man of Agnus, by name Leos. This man reported to Theseus the designs of the Pallantidae.
Theseus then fell suddenly upon the party lying in ambush, and slew them all. Thereupon the party with Pallas dispersed. This is the reason, they say, why the township of Pallene has no intermarriage with the township of Agnus, and why it will not even allow heralds to make their customary proclamation there of Akouete leo! (Hear, ye people!) For they hate the word on account of the treachery of the man Leos.
But Theseus, desiring to be at work, and at the same time courting the favour of the people, went out against the Marathonian bull, which was doing no small mischief to the inhabitants of the Tetrapolis.[*](An early name for a district of Attica comprising Marathon and three other adjacent townships.) After he had mastered it, he made a display of driving it alive through the city, and then sacrificed it to the Delphinian Apollo.
