What is the author's style in The Fourposter by Jan de Hartog?

The time frame of the play is significant to its central concerns. The six scenes, divided into three acts, span the years 1890 to 1925. The scenes take place anywhere from one to twelve years apart. The play as a whole thus provides an overview of key moments in thirty-five years of a marriage. Although this leaves large gaps of time in the reader's (or theatergoer's) knowledge of the marriage, it paints a broad, sweeping portrait of the relationship, highlighting the larger patterns of conflict, reconciliation, and change.
