Tigers of the Sea is a collection of fantasy short stories by Robert E. Howard about the pirate Cormac Mac Art, a Gael who joins a band of Danish Vikings during the reign of King Arthur.
(Historically, Cormac Mac Art is the name of a famous High King of Ireland, but among the many legends told of him there is no reference to him having been a pirate.)
The exception is "The Temple of Abomination", in which Cormac Mac Art and his Viking fellows defeat the last of the monstrous Serpent Men, whom King Kull fought in the much earlier Howardian cycle.
This edition included the same stories from Tigers of the Sea with an additional new story, "The Land Towards Sunset", published by author David Drake Originally, Cormac Mac Art (nicknamed an Cluiun - "The Wolf") was a member of the Irish Reivers - bold pirates who range far among the ruins of the Roman Empire, reaching Spain and on occasion even Egypt, though their ships are less sound than those of the Scandinavian Vikings.
He is impetuous, easily roused, and on bad terms with most of the other Viking leaders - though not overtly cruel and capable at times of surprising compassion.
Cormac Mac Art, though a formidable swordsman in his own right when in need, is a more subtle man: well-informed on the affairs of the numerous kingdoms, tribes, and factions inhabiting the turbulent British Islands and beyond.
He's also a fluent speaker of many languages, a competent spy able to infiltrate enemy strongholds, and the originator of complicated or intricate plots.
Andrew Offutt continued Cormac Mac Art's adventures beyond where Howard left off, writing no less than six such novels (some of them in collaboration with Keith Taylor).
In The Temple of Abomination Cormac tells his Danish companions about King Arthur - a view significantly different from that seen in the Arthurian legends.
..."Though Cormac obviously had some direct contact with Arthur and Lancelot before his exile from Ireland, they never appear onstage in the stories about him - most of which take place much further to the north, in the islands around Scotland.
Obviously, the Arthurian tales passed on to later generation would reflect only a small fraction of all these complicated conflicts occurring during Arthur's time.
