To trace the development of the Arts among the Lemurians, we must start with the history of the fifth sub-race. The separation of the sexes was now fully accomplished, and man inhabited a completely physical body, though it was still of gigantic stature. The offensive and defensive war with the monstrous beasts of prey had already begun, and men had taken to living in huts. To build their huts they tore down trees, and piled them up in a rude fashion. At first each separate family lived in its own clearing in the jungle, but they soon found it safer, as a defence against the wild beasts, to draw together and live in small communities. Their huts, too, which had been formed of rude trunks of trees, they now learnt to build with boulders of stone, while the weapons with which they attacked, or defended themselves against the Dinosauria and other wild beasts, were spears of sharpened wood, similar to the staff held by the man whose appearance is described above.
Up to this time agriculture was unknown, and the uses of fire had not been discovered. The food of their boneless ancestors who crawled on the earth were such things as they could find on the surface of the ground or just below it. Now that they walked erect many of the wild forest trees provided them with nuts and berries, but their chief article of food was the flesh of the beasts and reptiles which they slew, tore in pieces, and devoured.
