Ten patronages of Saint Eligius:
- Coin collectors
- Knife makers
- Corps of Royal Electrical and Mechanical Engineers
St. Eligius may be best known in the United States as the namesake of the hospital featured in the television show St. Elsewhere. He may also have inspired the name of the race of surface-dwellers in The Time Machine -- Eligius is known as Eloi in French. That's just baseless speculation on my part though.
