In Greek mythology, ichor is the sacred, non-human substance that circulates within the bodies of the gods, marking their separation from mortal beings. Unlike blood, ichor is imagined as pure, luminous, and incorruptible, reinforcing the gods’ immortality and untouchable nature. In poetry, the term is frequently used metaphorically to evoke divinity, supernatural strength, or an uncanny sense of invulnerability. Its appearance often signals a contrast between mortal fragility and divine endurance.

Origin: From ancient Greek ichōr, referring to the ethereal fluid of the gods. Historical context: Classical writers used ichor to distinguish divine beings from mortals; later poets adopted it symbolically to suggest purity, transcendence, or eerie vitality. Related terms: Ambrosia (the food of the gods), nectar (their drink), both associated with divine sustenance. Usage tip: In modern poetry, “ichor” often carries a mythic or elevated tone; overuse can feel melodramatic unless carefully grounded in context. Contrast: Mortal blood symbolizes vulnerability and decay, while ichor represents immortality and the supernatural.
