George O'Connor's Olympians series. Like the other books, this one is full of a great array of Greek myths featuring the titular character, and the contents of the book mirror and portray his personality. This a a beautiful book to look at, and it is structured around a series of presentations by the Nine Muses.
Python, establishing the Oracle at Delphi, becoming a patron of the arts, getting revenge on mortals who dare compare themselves to him, and turning his attention to a number of females (always with disastrous results). There is also a sizable section about his famed son Asklepios, the first doctor. Even though he was beautiful and full of song, Apollo's stories belie a dark side that emerges with each tale. This is a complex, entertaining, and thoughtful book, well worthy of the series. And like the other entries, it features copious endnotes, footnotes, and additional references for further reading.
All of the reviews I have read for this book have been laudatory. Shelley Diaz gave it a starred review and called it "A shining example of a graphic novel that educates and entertains. a fantastic and exciting introduction to this important god of ancient Greece." Kirkus Reviews commented positively about Apollo's portrayal as a tragic hero.
Apollo: The Brilliant One was published by First Second, who has a preview and much more available here.
