Henry T. Prinsep (1792–1878) was the son of a prominent East India Company servant, and like his father, Prinsep also spent much of his life in the East. He left Britain for Calcutta in 1809, at the age of seventeen, and stayed in India, working in a variety of roles, until his retirement in 1843. His brother James also lived in India and was a prominent scholar. Upon the latter's death in 1840, Prinsep found himself in possession of his brother's coin collection and a notebook, which became the basis of this work, published in 1844. Prinsep explains that the coins – which have inscriptions in both Greek and unknown languages – are valuable evidence of Alexander the Great's famous expedition to the east in the fourth century BCE. Prinsep also includes extensive illustrations of the coins, offering a fascinating view of an important archaeological discovery.
