命运的轮回仿佛在提醒人们，悲哀并非长久之物。国王和雅典人眼神中流露出对赫拉克勒斯女儿玛卡里阿远去的敬意。随后，一名使者带着喜悦与紧迫步伐向神庙奔来：“伊俄拉俄斯在哪里？我有好消息要告诉他！”伊俄拉俄斯从神庙旁站起，表情显得忧郁。

“你忘记了我吗？”使者问，“我是许罗斯的老仆人！不是赫拉克勒斯与德伊安尼拉所生之子吗？你知道，我主人的逃亡途中与你分别，他现在归来，与一支强大的军队同行。”周围的人欢呼声此起彼伏，这条消息迅速传遍了全城。

尽管年迈体弱，伊俄拉俄斯却穿上了盔甲拿起武器。他将孩子们和赫拉克勒斯的母亲留在城内，由雅典老人们照顾，然后自己带着一群年轻战士和国王得摩丰一路前行，以准备会师于许罗斯部下的军队。

两支军队聚集后勇敢地迎向欧律斯特塞的大军。当双方阵营相近时，许罗斯下车站在阵前的道口，对亚各斯特国王喊道：“欧律斯特塞国王啊，在这场血腥战争爆发之前，在两股拼搏仅为了少数利益而厮杀之前，请听我的建议：让我们两人独自一人决定胜负。如果我败给你的手，那么你可以带走我的兄弟姐妹，让他们听凭你的安排；如果你输了，那么，你应该把父亲遗留下的王权、宫殿以及伯罗奔尼撒统治权交还给我和我的亲属。”

士兵们欢呼支持这个提议，而面对面的士兵们也私下议论表示赞同。然而欧律斯特塞不再像过去那样胆怯，而是因为贪生怕死，他拒绝这个提议，不肯离开自己的军队，因此许罗斯又回到自己的队伍中。

占卜家与星象学家为战斗祈求祝福。战斗号角吹响了，是时候开始冲突了。

“公民们!”得摩丰国王大声呼唤，“你们正在为你们祖先的地盘而战，为你们城市的繁荣而战！”

另一边，欧律斯特塞也鼓舞他的士兵们为了亚各斯特与迈肯尼庆祝奋勇作战。但就在这一刻，号角吹响、盾牌碰撞、战车相撞、矛戟交错、剑光闪烁。在最初的一段时间里，他们坚定不移地推进，最终，他们展开攻势，将对方逐渐逼退。

双方激烈交锋，无数生命消逝于血泊之中。在混乱之际，一位老者的身影出现在前线——那就是被赋予青春力量的伊俄拉俄斯。他目睹许罗斯驾驶着战车追击敌人，就赶忙伸出了右手请求跳上战车代替位置。permitting him to take his place. Perseus respectfully stepped down, and Iolaos climbed onto the chariot. With renewed vigor, he charged forward.

As they approached the temple of Athena, Iolaos spotted Eurystheus's chariot fleeing before him. He prayed to Zeus and the goddess Eunomia for strength in this day of battle, seeking vengeance for Hercules. The gods granted his wish: two shining stars descended from above, settling on the horse's harnesses as a thick fog enveloped them all. In no time at all, the fog cleared and the stars vanished as mysteriously as they appeared; Iolaos had been rejuvenated.

Eurystheus fled into what he thought was a safe valley but found himself face-to-face with his pursuer once more. Unfamiliar with this man who chased after him, Eurystheus stood tall in his chariot and prepared to defend himself against this unexpected foe. Iolaos utilized divine power to knock Eurystheus off his chariot and subdue him before returning victorious with their captive back home.

The defeat of Eurystheus sent shockwaves through Aegisthus' ranks; without their leader, panic spread among them as they dispersed in disarray. The sons of Eurystheus were slain along with countless soldiers until not a single enemy soldier remained on Attican soil—the land was cleansed by bloodshed.
