Anarckhie is a square-serifed typeface in which the horizontal elements of the upper-case letters are below their midpoint, and the x-height of the lower-case letters is unusually small. There is some variation in the weights of the horizontal, vertical, and diagonal elements. The small x-height makes this typeface appear smaller than its point size would indicate, so text set in 12-point Anarckhie will appear much smaller than text set in 12-point BetterTypeRight. If you find it a little too unusual to use for straight text, consider it for text that needs a decorative touch.
The italic version of this typeface is at least as interesting as the plain version. The italics version may actually be more readable at small point sizes than the plain version, and the small x-height allows it to have long ascenders and descenders, and they give it a decorative look. It almost has the feel of a calligraphic face. Consider it when you need a very readable face but you also want something that is pretty and friendly.
