aspilogia

Etymology
Coined by Sir Henry Spelman circa 1595 as the title to his treatise on coats of arms, from ἀσπίς ("shield") + -λογία ("study of"). Sir Anthony Wagner argued in his Catalogue of Mediaeval Arms (1950) that on etymological grounds a better form of the word would have been "Aspidologia," but retained Spelman's innovation.

Noun

 * 1)  coats of arms, heraldry, armory (especially as a collection)
