is one of the names of the solar god, the offspring (Todt., 42, 19) of Nu and Nut. As a common noun the word unbu means the Hawthorn or some other kind of flowering bush. This god is called
‘the golden Unbu’ in the Pyramid Texts (Teta 39). We have no means of determining the exact sense of this word, which as an appellative expresses an attribute possessed both by the Sun and by the fruit, foliage, or other parts of the tree.
