The Arrows of Hercules is an historical novel by American writer L. Sprague de Camp, first published in hardback by Doubleday in 1965[1][2][3] and in paperback by Curtis Books in 1970.

[2][4] It is the fourth of de Camp's historical novels in order of writing, and second chronologically, set in the time of Dionysios I of Syracuse at the end of the 5th and beginning of the 4th centuries BC.

Having invented an improved type of catapult, he is drafted into Syracuse's war effort against Carthage by the tyrant Dionysios, creator of the first military ordnance department known to history.

"[6] Booklist noted its "[a]uthentic background and synthetic [sic: sympathetic] characters mingle easily in a story where action, color, page, and plot have the virile appeal evident in the author's The dragon of [the] Ishtar Gate.

She notes that "[t]he book is spiced here and there with some frank sexualities; otherwise its appeal would seem to be especially to young people interested in a story combining mechanical devices with adventure.
