Three variations of a cross symbol are depicted: the first has a vertical line intersecting a horizontal line with small crossbars at the ends (inherens); the second is a horizontal line with a vertical line resting on top (adherens); the third is a simple Greek cross (separata).

Oblique Intersection, Simple, Mixed, Multiple

Three variations of an 'X' symbol are depicted: a simple X (simplex); an X with double lines on one axis (mixta); and an X formed by triple lines on both axes (multiplex).
