Lapis-Lazuli
Both in Babylonia and in Egypt, lapis-lazuli was very highly valued, and this is shown by the use of its Assyrian name (uknu) in poetic metaphor. Thus, in a hymn to the moon-god Sin, he is addressed as the “strong bull, great of horns, perfect in form, with long flowing beard, bright as lapis-lazuli.”118 This may remind us of the “hyacinthine locks” of classical literature.
Lapis-lazuli, “a blue stone with little golden spots,” was a cure for melancholy and for the “quartern fever,” an intermittent fever returning each third day, or each fourth day counting in the previous attack.119
