FROM THE NAME CIANI Cyani was a low-grade gold coin circulating among African merchants whose value was 100 aspros. Aspro was a Turkish currency whose value has changed with the times. Cyan means blue, color of cyanotics for lack of oxygen, which in turn comes from cyan, color hydrocyanic acid, CHN, an extremely toxic compound, with which those condemned to death are killed in seconds by means of preventing in a fulminant way the circulation of oxygen in the blood. So Ciani sgnifica blue or bluish.
