Alpha and Omega (1915) is a collection of essays, lectures, and letters written by Jane Ellen Harrison and published for Harrison during the outbreak of World War I.
[1] In Alpha and Omega's preface, Harrison explains why she published such various topics, ranging from magic to post-Impressionism, in one work.
She says, "Seen in the fierce glare of war, these theories -- academic in origin and interest -- ... seemed like faded photographs."
(v-vi) World War I had brought a melancholy to Harrison's life because pacifist leanings, as admitted in the Epilogue, isolated her.
