In another thread, a poster had the view that Space Marines are virtually unknown and considered a myth by most imperial citizens.
I have a rather different view. I always thought Space Marines are fairly well known in Imperial society. Not necessarily on primitive and feudal worlds which are generally cut of from the wider Imperium in knowledge, tech level etc. but on Imperial worlds. That doesn’t mean that many people will have ever seen an actual Space Marine but these angels of death will be lauded as great heroes, their saga’s will be told and form an important part of the galaxy wide imperial culture, statues will have been erected of famous Space Marines, clerics will extol their victories in church, masses will be held when a hero dies etc. They won’t be a distant myth but rather heroes for the common people, much like saints I’d imagine. After all, they have been around for over 10,000 years. This will certainly be the case for planetary governors and senior officials who might be exposed to Space Marines. Knowing who and what they are would probably help….and every governor worth his salt is going to find out who ranks as a peer of the Imperium in case of precedent so chapter masters will be a familiar entity. Most of the fluff books and games also suggest Space Marines are hardly a secretive cult of super soldiers to the rest of the imperium (unlike the Deathwatch).
I’d also assume there are many historical works available to well connected historians filled with information (Just think of our own ancient historical works, from Greek poets to the Byzantium’s Strategicon and Tactica) as well as contemporary works and campaign histories (as mentioned in Imperial Armour fluff). Sure, knowledge is fragmented in the Imperium and the Inquisition likes to burn books but nobles, pupils from the schola and such other privileged people tend to have a decent education. In addition, there is the famous Tactica which spells out many military stratagems and forces, including Space Marines and some common tactics.
So I’d like to know what the majority view is on this. Do people think Space Marines in Wh40k are almost mythical beings with little grounding in actual life for the common imperial citizen or (like me) belief them to be an integral part of imperial culture?
