History of the Peloponnesian War

So they cut timber on Cithaeron and built a structure alongside the mound on either side of it, laying the logs like lattice-work I to form a sort of wall, that the mound might not spread too much.

Then they brought and threw into the space wood and stones and earth and anything else which when thrown on would serve to build up the mound. And for seventy days and nights continuously they kept on raising the mound, divided into relays, so that while some were carrying others might take sleep and food; and the Lacedaemonian commanders of auxiliaries together with the officers in charge of the contingents from the several cities kept them at their task.

But the Plataeans, seeing the mound rising, put together a framework of wood which they set on top of their own wall at the point where the mound was being constructed, and inside this frame they put bricks which they took from the neighbouring houses.
