Meanwhile Hippocrates made a levy in mass of the citizens, resident aliens, and foreigners in Athens, and arrived at his destination after the Boeotians had already come back from Siphae, and encamping his army began to fortify Delium, the sanctuary of Apollo, in the following manner.
A trench was dug all round the temple and the consecrated ground, and the earth thrown up from the excavation was made to do duty as a wall, in which stakes were also planted, the vines round the sanctuary being cut down and thrown in, together with stones and bricks pulled down from the houses near; every means, in short, being used to run up the rampart.
Wooden towers were also erected where they were wanted, and where there was no part of the temple buildings left standing, as on the side where the gallery once existing had fallen in.
The work was begun on the third day after leaving home, and continued during the fourth, and till dinner-time on the fifth,
when most of it being now finished the army removed from Delium about a mile and a quarter on its way home.
From this point most of the light troops went straight on, while the heavy infantry halted and remained where they were; Hippocrates having stayed behind at Delium to arrange the posts, and to give directions for the completion of such part of the outworks as had been left unfinished.
