This is a scholarly introduction, drawn from W. A. Clouston's 1881 anthology *Arabian Poetry*, to the 12th-century Yemeni scholar and poet Neshwân ibn Sa'īd (d. 1177 CE). The piece profiles him as a Himyaritic nobleman based in rural Hamdân whose learning drew on both classical Arabic texts and oral peasant tradition, and whose major lexicographical work, the *Shems el-'Ulûm*, was considered historically and geographically valuable by contemporary Orientalists. The text then introduces his best-known poem, the *Lay of the Himyarites*, an elegy on the fall of the ancient Himyarite dynasty of Yemen whose central theme is the universal decay of power and glory — a meditation the author acknowledges is philosophically commonplace. The distinctive argument is that the poem's real scholarly value lies not in its moral reflections but in its function as a compressed historical record: it preserves the names of otherwise unattested Yemeni kings and princes. Clouston's framing positions the *Lay* as evidence that the elaborate genealogies found throughout early Arabic literature are not invented fictions but rest on genuine historical tradition, with the poem serving as corroboration when read alongside the *Shems el-'Ulûm*. The text is aimed at a reader interested in classical Arabic literature and its use as a source for pre-Islamic South Arabian history.
