From Lowe's Curiosities of Heraldry: “It does not seem to have occured to these allegorizing worthies that the tincture of a charge may be diametrically opposed to the signification assigned to the charge itself. For example, the coat ‘Vert, a bull's head or’ by the armilogical rules cited above, would signify, as to the tinctures, pleasure and joy, while as to the charge it would mean rage and fury. Again, ‘Purpure, a wolf argent’ would mean ‘a wrangler with a peacable disposition!!’”
I'm an Academic Herald. I'm not a "real" herald; I don't design and register people's coats of arms (though I can certainly suggest designs for those who might be interested). What I do is study, research, teach, and write about heraldry. (You can find some of my books about heraldry and a list of my articles and presentations about heraldry at "Our Website" below.) And I like to share what I have learned about heraldry, hence this blog. I hope that you'll find it informative, interesting at least occasionally, and worth your time to come back. Got a question? Comments? Feel free to ask or let me know. I'd love to hear from you. You can find my contact information in my Profile.
Another coat of arms that can be found on the Titche-Goettinger Building, of which building I spoke on this blog recently, in downtown Dallas is the arms of Spain, or at least, the quartered arms of Castile and León.
Overall, I find the design interesting, in that it can be taken as a comparatively simple shield (of Castile and León) on one of those florid shield shapes where parts of the edges are formed into rolls, a style popular in the 16th Century, which is placed on a shield shaped like a chamfron (horse head armor) popular in Italy in the 16th Century, itself placed on another one of those florid “scroll-ly” shields. (The styles are dated according to the chart of shield shapes in Ottfried Neubecker’s Heraldry: Sources, Symbols and Meaning.)
Why Spain, on the streets of Dallas? Well, because, of course, what is now Texas was originally claimed by Spain, before it was claimed by France, and later by Mexico, prior to becoming an independent republic.
