διαυγής

transparent

Definition

διαυγής describes something that is transparent or translucent, allowing light to pass through clearly. In its only New Testament occurrence, it specifically refers to the material of the heavenly city's main street, which is 'pure gold, like transparent glass' (Revelation 21:21). The word emphasizes a state of perfect clarity and purity, where nothing is hidden or obscured. It conveys the idea of a substance so refined and pure that it possesses a luminous, see-through quality.

Biblical Usage

This word is used only once in the New Testament, in Revelation 21:21. It is employed in the apocalyptic vision of the New Jerusalem to describe the gold of the city's main street. The usage is highly descriptive and symbolic, contributing to the portrayal of the city's divine, radiant, and incorruptible nature. The context is one of ultimate purity and heavenly glory.

Etymology

Derived from the preposition διά (dia), meaning 'through,' combined with a root related to light or brightness, possibly connected to αὐγή (augē), meaning 'radiance' or 'light.' Thus, the compound word literally means 'shining through' or 'transparent.' It describes an object that does not obstruct light but allows it to pass, creating a luminous effect.

Semantic Range

Theologically, διαυγής is significant in depicting the perfection and glory of the New Creation. Its single use to describe the gold of the New Jerusalem's street (Revelation 21:21) symbolizes the absolute purity, holiness, and unhindered divine presence in eternity. The transparency signifies there is no impurity, deceit, or shadow—everything is open and radiant in God's light. Understanding this Greek term enriches the reading of Revelation by highlighting the material and spiritual perfection of the future reality God prepares for His people.

In the ancient world, truly transparent materials like clear glass were rare and highly valued, often associated with luxury and purity. Gold was the standard for incorruptible value and divine association. Describing gold as 'transparent' would have been a striking, almost paradoxical image to first-century readers, emphasizing a supernatural quality beyond ordinary precious materials. It points to a reality transformed by God's glory.

καθαρός (katharos, G2513) — means 'pure, clean,' focusing on freedom from contamination, but does not inherently imply translucency. φωτεινός (phōteinos, G5460) — means 'bright, luminous,' describing something that emits light, rather than allowing light to pass through it.
