Lucasta is a feminine name from seventeenth-century English literature. It is associated with the poet Richard Lovelace, whose collection Lucasta: Epodes, Odes, Sonnets, Songs, &c. appeared in London in 1649. The name is traditionally interpreted as a literary formation from Latin lux casta, “chaste light” or “pure light.” It is not an inherited ancient Roman name and is not primarily a hereditary surname.
Meaning and Latin Construction
The conventional explanation has a sound linguistic basis. Latin *lūx* is a feminine noun meaning “light,” while *casta* is the feminine singular form of castus, “morally pure,” “chaste,” or, in some contexts, “pious” or “sacred.” The two words can therefore agree grammatically as “chaste light.” Susan A. Clarke's study of Lovelace renders the phrase as “pure, chaste, pious or sacred light” and identifies a play on it in the “chaste breast” of To Lucasta, Going to the Warres.
The spelling Lucasta is a shaped poetic name, not the unchanged Latin phrase: writing lux casta without its space would not by itself produce the exact spelling Lucasta. It is therefore more precise to call Lucasta a Latinate literary coinage based on the phrase than a Latin personal name. The gloss describes the poet's idealized figure; it does not describe the character or ancestry of someone who later receives the name.
The Name in Lovelace's 1649 and 1659 Books
The firm historical starting point is print. The Folger Shakespeare Library catalogue identifies the first book as Lucasta: Epodes, Odes, Sonnets, Songs, &c. To which is added Aramantha, a pastorall, printed in London by Thomas Harper for Thomas Ewster in 1649. Clarke adds unusually specific publication evidence: the volume was entered in the Stationers' Register on 14 May 1649, and bookseller George Thomason dated his copy 21 June 1649, showing that it was circulating by then.
Lucasta is more than the book's title. The collection includes poems addressed to the figure, among them To Lucasta, Going to the Warres and To Lucasta, Going beyond the Seas. A second collection, *Lucasta: Posthume Poems*, was printed in London in 1659 after Lovelace's death; the University of Michigan's full-text contents show another group headed “To Lucasta.” The repeated use makes Lucasta an enduring addressee or persona in Lovelace's poetry, although it does not establish the civil identity of a woman behind the poems.
The first volume belongs to the political and literary world of the English Civil Wars. Clarke describes its poems as interventions in Royalist debates rather than merely private love lyrics. This context matters because Lovelace's Lucasta can function at once as a beloved figure, an emblem of chaste love, and part of a poetic argument about honour. Treating every poem as straightforward biography misses that literary work.
Was Lucasta Lucy Sacheverell?
The familiar identification is possible but unproved. Anthony Wood's Athenae Oxonienses (1691–92) says that Lovelace courted a wealthy woman named Lucy Sacheverell, called her Lux casta, and lost her when she married after a false report that he had died from a wound at Dunkirk. Wood wrote decades after the events, and this romantic narrative is not confirmed by the 1649 title page or by the poems themselves.
Modern research makes the uncertainty concrete. Clarke reports that no researcher had securely identified “Lucy Sacheverel” in historical records and allows that Wood may have had the name wrong or that Sacheverell could have been the surname of the man she married. W. C. Hazlitt's 1864 edition had already questioned Wood's story, noting that the change from Lucy Sacheverell to Lucasta was not an obvious nickname formation.
The careful conclusion is therefore limited: *Lucasta was Lovelace's poetic name for a female figure; the phrase lux casta informs its meaning; the equation of that figure with a particular Lucy Sacheverell remains a later biographical tradition.* It should not be presented as a documented engagement or used to attach modern bearers to either family.
A Name in a Seventeenth-Century Literary Tradition
Lucasta did not arise in isolation. English poets of the period used fashioned names for women addressed in verse. Clarke identifies a particularly relevant relationship with William Habington's Castara, the name in his 1634 collection: she explains Castara as “chaste altar” and Lucasta as “chaste light,” both drawing on Latin castus. She also argues that Lovelace's poetry responds to Habington's language of chaste love.
This comparison helps explain how the name was made, but Castara is not a spelling variant of Lucasta. Nor are Lucy, Lucia, Lucetta, and Lucretia automatic variants merely because they begin with similar sounds or letters. Lucy may have influenced the wordplay reported by Wood, yet Lucasta's documented explanation depends on the complete poetic construction.
**Locusta** is also a different name. It is the ancient Roman name attached to the poisoner associated with the courts of Claudius and Nero. Similar spelling does not make Locusta the source of Lucasta, and the traditional lux casta interpretation points in another direction.
From Poetic Name to Given Name
The modern name reference *Behind the Name* classifies Lucasta as a feminine literary name. Given the documented seventeenth-century formation, its later use as a given name is best understood as adoption from Lovelace's poetry rather than continuation of an ancient Latin naming tradition. That route does not mean every parent chose it for exactly the same reason, and the name alone does not justify claims about a bearer's nationality, religion, or family background.
An isolated appearance in a database's surname field is not enough to establish a general “Lucasta family-name origin”; it may reflect reversed name order, indexing, or an individual family's distinct history. Etymology explains the literary formation, while genealogy requires records connecting particular people.
