Summary: Fascinating Tale About The Riddle & Compass History
Comment: The reviews of this book go from one extreme to the other- are you confused about reading this book? As one reviewer suggested to the naysayers- lighten-up! I agree. This book is well presented and covers far more than the "riddle" of who invented the navigational compass, although that alone is worth the read.
The history of the compass starting with the ancient Chinese discovery of the magnetic qualities of lodestone and applying that knowledge to construct a land use compass, then following the invention around the world and over centuries until it was discovered to be useful for sea navigation and it's design perfection as it traveled from one country to the next up to contemporary times, is also worth the read.
Aczel's treatment of this subject includes his account as a young man and his own time spent in the pilot house of ocean liners learning navigation from his seafaring father and captain. He learned the importance of a compass as a navigation aid and this was a great prelude to writing with hands-on knowledge.
Some of the naysayers have attempted to dilute the importance of the compass as a navigational aid- hah! Like Aczel, I too, have spent much time on the ocean and for those that think sailing without a compass is no big thing, consider the older tools of navigation, i.e., guiding by the stars, etc. What do you guide by with during cloudy skies, turbulent seas and no land in sight for weeks or months on end? The compass is unaffected by those conditions and it also lead to accurate, cross-ocean, long distance mapping of the entire world. And they said that's no big thing???? Landlubbers- sheesh!
After finishing this book, I read "The Compass" by Paula Z. Hogan, 1980. Although it was writen for children 9-12, it is a great read for all ages, very informative and at only 60 pages long plus illustrations and experiments, packs more relevant compass info than any book I've read and is great companion to Aczel's book.

Summary: A good, readable narrative
Comment: Amir Aczel spent his childhood on the Mediterranean Sea--literally--sailing around in and sometimes steering a passenger ship that was captained by his father. This romantic personal history makes Aczel particularly suited to tell the story of the compass, which so improved navigation in the late thirteenth century that it sparked a commercial revolution and made possible the Age of Exploration that was to follow.
In his highly readable narrative Aczel provides a brief history of navigation centered on the compass--from navigation by stars and sounding lines to the naval supremacy of the Venetians in the 14th and 15th centuries to the masterful sailing of the great explorers--da Gama, Magellan--who opened up the world in the 15th and 16th centuries. We learn, too, about the early invention of the compass in China, where it was evidently not used at sea, and of its perfection as a naval instrument in the Italian city of Amalfi.
The Riddle of the Compass is at its best when Aczel discusses the actual "riddle" to which the title of the book refers: the question of the historicity of a certain Flavio Gioia, whom the people of Amalfi credit with having invented the mariner's compass in 1302. Most interestingly, the question of this Gioia's existence involves the correct interpretation of a single Latin phrase, a reference to the invention of the compass in an early 16th century commentary on the poetry of Lucrezio Caro.
Readers of Dava Sobel's popular book Longitude, which tells the story of the invention of the naval chronometer, will enjoy Amir Aczel's equally readable history of the compass.

Summary: What was the riddle?
Comment: There are a variety of interesting facts presented, but the narrative fails. Aczel organizes his comments around a visit to Amalfi, Italy. According to the book, he arrives in Amalfi to celebrate the birth of Flavio Gioia, a celebrated 13th century Amalfi native whom locals credit with inventing the compass. Wanting to know more about Flavio, he goes to an Amalfi library for research reading. The result is this little tome. At the book's conclusion, our investigative reporter looks up at the understanding librarian, provides words of appreciation and leaves.
We then learn that the first known use of magnetic direction devices was Chinese divination practice, now known as Feng Shui. It seems the first use of a compass was architectural. The Chinese liked having their front doors facing the auspicious south. Sometime around 1100, someone in Italy discoved Feng Shui navigation. It seems Feng Shui architectural tools were equally useful for turning a boat's bow to the south. Further, the always inventive Italians put the device in a box for easy divination during off shore religious services. This was particularly useful during inclement weather.
I guess the 'riddle' was 'who was Fabio Gioa?', but this pleasant chunk of local folklore is quickly dismissed as legend springing from a missing comma in some 15th century manuscript. An alternative might have been 'who invented the compass,' but it is clear this cannot be deduced. A third mystery involves the changing 'compass rose'. On ancient maps, there were 12 directions. Sometime during the 13th century, maps started using a 16 direction 'compass rose'. Who or what sparked that change?
While these issues have the makings of an excellent story on the social shaping of technology, the author never really bring the issues into focus. There are lots of curious details, but the author forgets the punchline.
A lot of time is spend speculating on who 'invented' the compass. Since the familiar European compass is little more than a boxed Chinese 'pivoting magnetized needle', it isn't clear the 12th century Italian design is really an 'invention' at all. This could have provided an interesting segway to an investigation of 'creation' myths in general. It seems many medieval technological imports from China and/or the Muslim Caliphates get transmuted from 'import' to 'invention' in the 16th century. Why these myths were so important, and still offered credibility seems an important topic, but Aczel only alludes to the issue.
