Lucasta in the poem: To Lucasta going to the wars
Who Is Lucasta?
.......The identity of the woman to whom Lovelace addresses the poem is uncertain; she may even have been a product of Lovelace's imagination. However, evidence suggests she was Lucy Sacheverell, whom he sometimes called by the Latin name Lux Casta. Lux, a noun, means light; casta, an adjective, means chaste, moral, virtuous, pure, sacred. Thus, Lux Casta may be translated as Pure Light or Sacred Light.
