Translate into English : Unctis falciferi senis diebus, Misce dimidios, puer, trientes, COMPOSITION. 2. Translate into Latin : MARTIAL. There were other and worse forms of lawlessness, which the plague introduced at Athens. Men, who had hitherto concealed what they took pleasure in, now grew bolder. For, seeing the sudden change,-how the rich died in a moment, and those who had nothing immediately inherited their property, they reflected that life and riches were alike transitory, and they resolved to enjoy themselves while they could, and to think only of pleasure. Who would be willing to sacrifice himself to the law of honour when he knew not whether he would ever live to be held |
