Example coats of arms[edit]

The arms of Sandwich, England would be an even better example than the arms of Hastings, since they are purely dimidiated (without the middle lion on top), but we don't seem to have a Wikipedia image. There are also the lions dimidiated with fish of Yarmouth, but we don't seem to have that either... AnonMoos (talk) 18:57, 27 February 2010 (UTC)

Are the "strange hybrid" images (like the one of a rabbit dimidiated with a fish) meant only as illustrations(and thus be somewhat exaggerated) or is there any historical basis for either of them? I was just a bit confused since the Rabbitfish smells too much like an astrology joke (Chinese zodiac sign of the Rabbit roughly coincides with the western Pisces) (talk) 20:20, 10 April 2010 (UTC)

The example of the half-lions/half-ships really is famous in English heraldry (see Fox-Davies). As for the rabbit-fish example, I don't know much about it, but if you go to the image description page, you can see that it's used in a number of articles (Gmina Prochowice, Prochowice etc.), and further articles on Polish Wikipedia, so it certainly seems to be authentic as far as that goes...

Deleted image of horizontally dimidiated fish & rabbit. Looks like a modern Walt Disney mock-up. Not a part of the heraldic "canon" as far as I am aware. Misleading. No source supplied. This is not a valid example of dimidiation. Pasted here for the record: (File:POL Prochowice COA.svg|thumb|Horizontally dimidiated rabbit and fish) (Lobsterthermidor (talk) 18:18, 7 February 2011 (UTC))
It occurs on the various Encyclopedia pages about the relevant geographical locations -- as already explained in the previous remarks above -- and it's used on 25 pages on Polish Wikipedia, so it's quite unlikely that it's any kind of hoax. Unless you have specific deep knowledge about Polish heraldry, it might be better to refrain from making sweepingly dogmatic statements based on generalizing from insufficient data which might be perceived as arrogant.

Also, your new substitute images might be impeccably historically authentic, but they have problems as illustrations for use in making clear the concept of dimidiation -- in the banner, the lions and hulks are both Or, so the dimidiation line is kind of partially blurred, while the seal is only "semi-dimidiated". You also didn't adjust the article text to reflect the change of images. The end-result was really not more helpful than the state of the article before you started editing. P.S. You can find a lot of full-color semi-dimidiated images with half of an eagle etc. on Wikimedia Commons (File:Wappen_Landkreis_Nordwestmecklenburg.png is one of probably hundreds), but you might not choose to recognize their existence, since they come from central/eastern Europe...

I'm sorry my edit appeared arrogant, as you say, I apologise. It is one of my bugbears that images are sometimes used without sources to give them credibility. I have looked at the links you refer to and have found that it is the armorial of Prochowice town in Poland, which I have now noted on the caption. I think it is important to inform the reader that such forms are unheard of in English heraldry, I can not find a reference in any of my sources. As far as I can see the majority of English WP's heraldry articles are about English heraldry, quite logically. It is too broad a subject to treat on a universal basis. I don't know anything about Polish heraldry, i.e. whether it is governed by the same rules as English, we must be careful not to mix different systems in the same article which may operate under different rules, unless the issue is discussed in the text.
