Van Rijn And Flandry

Nicholas van Rijn is first seen in "Margin of Profit" and last seen in Mirkheim. These are the opening and closing instalments of the Polesotechnic League sub-series of Poul Anderson's Technic History. Fortunately, however, the sub-series is not just about van Rijn who:

is off-stage in five instalments;

cameos in one;

receives reports from other characters in two;

shares the stage with other continuing characters in four -

- most noticeably in the second last instalment, "Lodestar," which features van Rijn and all three members of his trade pioneer crew and his granddaughter, Coya Conyon, and members of the Ythrian species who also have their own sub-series of the Technic History.

That leaves only four other instalments about van Rijn.

Dominic Flandry is more up front in his period:

twelve instalments starring Flandry;

one in which he cameos three times (i.e., a lot);

two others.

The instalments in which he does not appear inform us of conditions, characters and events on the planets, Freehold and Aeneas. The novel in which he cameos does the same for the planets, Imhotep and Daedalus. Thus, although there is a lot of Flandry,  there is also more than Flandry.
