Comparing Poul Anderson's works with those of his contemporary and fellow
Campbell future historian, James Blish, has refocused my attention on Blish and I will shortly add to the
James Blish Appreciation blog.
Blish commended Anderson's Tau Zero and After Doomsday. In particular, he appreciated the passage of the relativistic spaceship through the period of inter-destruction in Tau Zero and also the recounting of the Battle of Brandobar not in the narrative present but in a later-sung ballad in After Doomsday.
Although Blish understood that Anderson particularly liked his flamboyant merchant prince character, Nicholas van Rijn, he also thought that that character was about played out. However, I think that the van Rijn sub-series of Anderson's Technic History had just about come to an end by the time that Blish expressed that opinion. Because I had been a Blish fan long before I became an Anderson fan, I asked Blish's advice on reading Anderson and, as part of this, asked whether I should disregard Dominic Flandry. Blish agreed with this suggestion at the time! I now realize that it was entirely mistaken, of course. The Flandry series became much more than its earliest-written segment, the "Captain Flandry" series, which continues to be worth anyone's attention in any case.
Blish appreciated and made multiple references to CS Lewis. He valued the moral and psychological insights in That Hideous Strength and The Great Divorce and the chilling account of Weston's possession and damnation in Perelandra and, for these reasons, wished that Lewis had written more fiction.
He also preferred ER Eddison's The Worm Ouroboros and Zimiamvia Trilogy to Tolkien's Middle Earth History. It seems that some readers like Eddison or Tolkien but not both. I could not get into Eddison and have read little Tolkien - The Lord Of The Rings only twice.
All of this is relevant to Poul Anderson. I regard CS Lewis' Ransom Trilogy as a Christian response to twentieth century science fiction falling, both chronologically and conceptually, between Wells and Stapledon earlier in the century and Blish and Anderson in later decades. And Anderson was transforming Norse mythology into modern fantasy at the same time as Lewis' friend and colleague, Tolkien - although more people know about The Lord Of The Rings than about The Broken Sword.
