As most of the books (that I know of) on this subject, this book can be thematically divided into two parts, the first on gods, the second on heroes. Tsiforos has organised the book into several short - uniform in length - stories, each being ~8 pages long. I suspect that this was done because it was originally written in parts, in the form of articles for the Greek magazine "韦伪蠂蠀未蟻蠈渭慰蟼" in the 60s. Tsiforos is very eager to show that Greek Mythology has strong links with mythologies of other eastern civilisations. These arguments often have deviated the focus from the actual stories and have made reading of the long book somewhat boring at places (especially in the earlier part of the book). Nevertheless, the fact that the book is divided into small chapters make it easy to read on and off over long periods of time. Tsiforos's humour in this book is often cheap - but charming - and usually reminiscent of greek movies of that era (some of which he had actually provided the scripts for!). I have to admit that I remember his "Crusades" book more fondly.
This particular edition is complete; I see that other two-volume editions have also been added to 欧宝娱乐. If I were to choose a two-volumed edition and read only one of the two volumes, then I would probably go for Volume Two, which would include the stories on heroes. This second part is more light-hearted and more enjoyable to read.
