Also called Rabdology (from Greek ραβδoς [rabdos], rod and λóγoς [logos], word).
Napier published his invention of the rods in a work printed in Edinburgh at the end of 1617 entitled Rabdologiæ.

Amazon.com: Rabdology (Charles Babbage Institute Reprint): Books: John Napier,William F. Richardson
John Napier had already discovered and published an epoch­making treatise on logarithms when in 1617 he turned to "rabdology" or rod-reckoning as yet another means by which to confront the problem of simplifying the huge calculations involved in multiplication, division, and the extraction of roots.
This first English translation of Napier's Rabdologia provides a clear and readable introduction to a group of physical calculating devices, which, long overshadowed by Napier's logarithms, have their own intrinsic interest and charm.
