In Genesis, what material was the window of Noah’s Ark made from?

Genesis does not specify what material Noah’s Ark window was made from.

Genesis 6:16 instructs Noah to make a window, or opening, for the Ark and to finish it within a cubit of the top. The passage describes its placement and approximate size, but it does not say whether the opening was covered with wood, cloth, a transparent substance, or anything else.

This detail is easy to overstate because modern illustrations commonly show glazed windows or open hatches. Glass windows would be an anachronistic assumption for the ancient setting, and the biblical wording is not precise enough to identify a construction material.

Translations also differ in how they render the Hebrew term, using “window,” “opening,” or a related expression. Those variations reinforce the safest answer: Genesis specifies the feature’s location and dimensions, not its material.
