I want to know the answer to the following question:
Name one author who is less frequently the subject of a variorum.
All the background I'm provided with is that "The collation of all known variants of a text is referred to as a variorum, namely a work of textual criticism whereby all variations and emendations are set side by side so that a reader can track how textual decisions have been made in the preparation of a text for publication.". Is that enough to answer the question?
Answer: no
