Summary: Not the best sundial book available
Review: I found Rohr not to be as useful as the two other texts by Waugh or Mayall and Mayall. The other books are more clear and practical in the constructions of many different types of dials. The only strength of the Rohr test is the explanation of (i) drawing hour lines on any surface so long as you have a rod shaped gnomen and (ii) the construction of babylonian and Italian hours. Even so the explanation of the babylonian and Italian hours could be better. So the Rohr book would best be used as an adjunct to the other texts but if you are just starting out, buy the book by Waugh first then Mayall and Mayall and then perhaps Rohr if your library hasn't got it.

Summary: Another great classic on sundial construction...
Review: This book is another of the must-have's for anyone interested in understanding or building sundials. It has a lot of the theory behind how they work and how to make some of the different types of dials. I recommend this title highly!
