This book was created when John Watson McCrindle lived and worked in India as a schoolteacher. His interest in the state poured into years-long research of the ancient Greek and Latin text, where he collected the mentions of India. For this research, he collected materials from the works by Arrian, Q. Curtius, Diodoros, Plutarch, and Justin. The book follows Alexander's invasion in India, with all the great leader's campaigns on his way, including his invasion in Afghanistan, the Panjâb, Sindh, Gedrosia, and Karmania.
