The way Wikipedia grows is to start something more general and often people show out of nowhere and expand it For example consider this I only wrote  sentences basically to park that painting and without any major effort from me other people made it a pretty nice article I think the more general issue is the Textual analysis of the gospel of Mark because it will not have objections regarding notability GW Youngs focus on a part of Mark will work well as a significant section and will attract other analysis In one year that may well grow like the San Cassiano article Please give me a few days and I will think how we can start it and then wait for it to gorw  either others will do it or we will do it ourselves in
