Needless to say, the majority of scientific community considers the entire Fomenko’s work to be pseudoscience, although it has a number of followers. In my opinion, what it reminds me most is one giant, elaborate hoax, for it is way too eccentric to be treated seriously. If everything before certain date is a reflection of later events, what to do with objects from that period that do not fit into any later time? What about written sources? Were they all falsified by some immeasurably powerful organization that had enough time and effort to spare to write and distribute them, destroying everything that doesn’t fit?
Plan B: Use Plan B if you have only a few, larger similarities or differences. After your introduction, in the next paragraph discuss one similarity or difference in BOTH works or characters, and then move on in the next paragraph to the second similarity or difference in both, then the third, and so forth, until you're done. If you are doing both similarities and differences, juggle them on scrap paper so that in each part you put the less important first ("X and Y are both alike in their social positions . ."), followed by the more important ("but X is much more aware of the dangers of his position than is Y"). In this format, the comparing or contrasting goes on in EACH of the middle parts.
