You know, it's funny... with the rather fervent responses my
little comment got, you'd think I came in here, peed on a copy of the Conan core book and stepped on a puppy's head.
So disparate eras must mold into one convention of dress, technology and science. In my case, dark ages, antiquity and fantasy conspire to achieve this.
This is pretty much exactly my point.
Concerning Hyborian heavy cavalry, I never read anything about knighthood with a dubbing ritual and many nobles from the kingdoms were no fighters but rather leaving in the court.
Note: I didn't say Hyboria uses the exact same conventions as medieval Europe. But it certainly has knights of a sort. The Black Dragons are a good example of this.
Held only unto themselves, the Black Dragons could theoretically fit into any timeline. They could be Alexanders cavalry, for instance.
But mix their existance with plate armour and an abundance of Feudal societies and to me.. that makes them a close approximation of European knights.
The Hyrkanians, if anything, resemble Mongols -- 13th century.
Even just reading the gaming books -- it appears even Vincent (I may be wrong on this) notes the importance of cavalry in most societies - which is a convention of the medieval period, before which infantry predominated the battlefield with only very small groups of cavalry operating on only specific commands.
The equipment available is medieval. Many of the governments are medieval. Tactics seem to be medieval. Dress, even, often seems medieval.
The majority of Hyboria immediately reminds me of real medieval history. There are certainly LATER-era concepts (Zingara is certainly, at least, late medieval) and earlier-era concepts (Stygia has plenty of ancient-world concepts in it, although I'd still say it also is a fit for medieval southern Egypt in a lot of ways).
But all fantasy, as I said before, has different eras designed into it, which doesn't change the majority. To use the same example from earlier -- Middle-earth is no LESS Migration-period just because the Crown of Gondor was ancient Egyptian in style, or because the Numenoreans were clearly based on pseudo-Greek Atlanteans.
Anyone is free to disagree of course. How -you- see the world is your business. I'm just saying that's how -I- see it.
