Name
In the catalogue of stars in the Calendarium of Al Achsasi Al Mouakket, this star was designated Thanih al Naamat (تاني ألنعامة - taanii al naʽāmāt), which was translated into Latin as Secunda Struthionum, meaning the second ostrich. This star, along with η Cet (Deneb Algenubi), τ Cet (Thalath Al Naamat), ζ Cet (Baten Kaitos)and υ Cet, were Al Naʽāmāt (ألنعامة), the Hen Ostriches.
In Chinese, 天倉 (Tiān Cāng), meaning Square Celestial Granary, refers to an asterism consisting of θ Ceti, ι Ceti, η Ceti, ζ Ceti, τ Ceti and 57 Ceti. Consequently, θ Ceti itself is known as 天倉三 (Tiān Cāng sān, English: the Third Star of Square Celestial Granary.)
