Sable, the deep black so often found in Heraldry is believed to named from an animal of the marten family know in the middle ages as a Sabellinœ and noted for its very black fur 1A Glossary of Terms used in British Heraldry, J.H.

In engravings, when colors cannot be shown it is represented as closely spaced horizontal and vertical lines, and appropriately is thus the darkest form of hatching, as this method is known 2Boutell’s Heraldry, J.P.

Mediaeval Europe was a deeply religious and Christian and many of the nobility wanted to show their devotion by adopting the symbol of the cross as part of the arms. Since no two arms could be identical there arose many variants of the cross, typically involving patterning along the edges 8Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P67, or fanciful, decorative endings to the arms of the cross 9A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P128. The cross pattee fitchee is typical of these, pattee indicating that the upper arms spread out at the ends, fitchee showing that the lower arm ends in a point as if is to planted in the ground.
