   • 1912, Edward Salisbury Dana, A Text-book of Mineralogy with an Extended Treatise on Crystallography and Physical Mineralogy, New York: John Wiley & Sons, E.2.(b), page 417:

     Aplome (properly haplome) has its dodecahedral faces striated parallel to the shorter diagonal, whence Haüy inferred that the fundamental form was the cube; and as this form is simpler than the dodecahedron, he gave it a name derived from ἁπλόος, simple. Color of the original aplome (of unknown locality) dark brown; also found yellowish green and brownish green at Schwarzenberg in Saxony, and on the Lena in Siberia.
