The E-Sylum: Volume 4, Number 9, February 25, 2001, Article 4


Lawrence Lee of the Durham Western Heritage Museum (home of the Byron Reed collection) writes:

"The recent E-Sylum discussions over the correct term for various anniversary dates caused me to turn to the definitive work on time in numismatics, Tempus in Nummis.

In Volume 2, beginning on p165 of their metacognitive work, authors James Sweeny and Robert Turfboer devote an entire section to the language of anniversaries. Among their factoid gems: a tertiomillennial marks an anniversary of 333 years, while a sesquibimillennial occurs every 2,500 years. Which will be about how long it will take anyone to surpass Sweeny and Turfboer in covering the subject."

[Editor's note: Hail to Sweeny and Turfboer! And shame on me for not going to my bookshelf before asking my original question. Of course, if I hadn't brought the subject up, we'd have missed everyone's interesting replies. Tempus in Nummis, published in 1992 by Numismatics International, is one of my favorite numismatic books, and I'm glad to see others think likewise. ]
