All four hymns exist primarily in Sanskrit. Traditional sources and later anthologies commonly ascribe them to **Ādi Śaṅkarācārya (8th century CE)**, the philosopher-saint who consolidated Advaita Vedānta and composed numerous devotional hymns (*stotras*) to deities such as Śiva, Viṣṇu, Durgā, and Subrahmaṇya. While historical proof of authorship is impossible to verify, internal features—concise meter, balance of philosophical and devotional diction, and the recurring refrain *"tad praṇamāmi Sadāśiva liṅgam"* in *Lingashtakam* or *"eka bilvaṁ śivārpaṇam"* in *Bilvashtakam*—are consistent with the *Śaṅkara stotra* style. Their earliest manuscript witnesses appear in Sanskrit stotra collections circulating by the late medieval period. By the seventeenth and eighteenth centuries they were integral to pan-Indian Śaiva worship manuals and were quoted in ritual commentaries.
