Aspilogia

ASPILOGIA, n. 

Pronunciation:  /as.pi’ ło gi.a/

plural  aspilogiae

1. Heraldry, coats of arms, armory (especially as a collection)

Etymology:  Coined by Sir Henry Spelman c. 1595 as the title to his treatise on coat armour. Sir Anthony Wagner argued in his A Catalogue of Mediaeval Arms (1950) that on etymological grounds a better form of the word would have been “Aspidologia,” but retained Spelman’s innovation.
