Mundy dedicated Tros of Samothrace to his friend Rose Wilder Lane, who had funded its book publication.

[1] The novel concerns the courageous adventures of the title character (a Greek from Samothrace) as he helps pre-Roman Britons fight the invading forces of Julius Caesar.

The novel also imagines a benevolent secret society of mystics which includes the British Druids and the followers of the Greek Samothracian Mysteries.

Although the stories were popular with Adventure's readers, they also aroused debate due to the fact that Mundy described Julius Caesar and Roman civilization as imperialistic and tyrannical; Adventure editor Arthur Sullivant Hoffman later stated that the Tros stories were the most controversial the magazine had ever published.

[5] Leiber also said that "Talbot Mundy’s Tros of Samothrace is one of the half-dozen novels I have re-read most often in the course of my life, or rather during the thirty-eight years since I first devoured it.
