This poem personifies Ares, the Greek god of war. It describes Ares as enjoying the sounds of battle - the thunder of guns and roar of cannons. It suggests that many leaders throughout history have started wars out of personal ambition and glory, rather than for noble causes, and these conflicts have caused widespread death and destruction. The poem notes that while weapons of war have changed over time, from stone weapons to modern guns and bombs, war has been a constant part of human history. It indicates that all wars will ultimately lead to the final battle of Armageddon, when God will defeat the forces of evil and bring about a 1,000 year period of peace.
