"... Next Enoch encounters the cornerstone of the earth and sees the four winds that support the earth and firmament of heaven. The text reads as follows: “I saw the cornerstone of the earth. I saw four winds supporting the earth and the firmament of heaven.” The imagery of the cornerstone, the largest stone in the foundation that is positioned in the primary corner of a building, is recalled also in biblical texts. For example, in Job 38:6 God lays the cornerstone upon which he constructs the world. There are no indications in Job or in the Enochic text that the authors have any specific site in mind; rather it appears that the motif has been merely appropriated. The reference in 1 Enoch 18:2 to the cornerstone of the earth is intriguing, for on the surface a specific locale might seem to be inferred. Yet one is unable from the context of 1 Enoch 18 and Job 38 to adduce any setting for this interesting detail. Following the cornerstone of the earth, Enoch sees the four winds. The relationship of the cornerstone to the winds supporting the earth and firmament of heaven is not entirely clear. Nickelsburg proposes that the cosmos is depicted in this chapter as a building: the earth sits atop a foundation with a cornerstone, while the firmament rests on the ends of the earth and is supported by winds. One might surmise that the winds correspond to the four directions and blow from the four quarters of the earth.11 Martin understands ‘the four winds’ to be a Babylonian expression, although he notes within Babylonian cosmology that the winds of the four cardinal points did not support the earth or firmament. Homer also distinguishes the quarters of heaven by the four winds ..."
