How did Heracles manage to tame the Mares of Diomedes?

Heracles was tasked with capturing the Mares of Diomedes, which were known for their ferociousness and for being man-eating creatures. To successfully tame them, he fed their master, Diomedes, to them. This act of feeding the mares their owner not only eliminated the immediate threat that Diomedes posed but also served as a powerful psychological tactic, transforming the mares into more docile creatures. After consuming Diomedes, the mares lost some of their aggressive nature, making them easier for Heracles to manage and ultimately bring back. This approach highlights Heracles' cunning and strength, character traits central to many of his legendary feats.
