In the compendium's teaching frame, King Divodāsa of Kāśī, identified with
the medical deity Dhanvantari, instructs Sushruta and other pupils. This
locates the work within an authoritative lineage; it is not independent
evidence that one author practised every operation at a datable court. The
earliest firm association between the name Sushruta and this medical
tradition appears only in the sixth-century CE Bower Manuscript.

Philological evidence instead points to several periods of composition and
revision. An older work comprised five sections. A long sixth section, the
Uttaratantra or “Later Treatise,” now makes up more than a third of
the compendium. The early manuscript colophons that call the work the
Suśrutasaṃhitā together with the Uttaratantra preserve the memory
of that joining. Exactly which passages belong to which hand remains under
study. 1
This layered authorship matters medically. The text ranges beyond operative
surgery into diagnosis, embryology, regimen, drugs, toxicology, paediatrics,
obstetrics, and diseases of the eye and ear. Its surgical material belongs
inside Ayurvedic explanations involving doṣas, bodily tissues,
channels, diet, season, medicines, and ritual obligations—not inside a
modern specialty detached from the rest of care.

Last centuries BCE: composition may have begun, although
no single starting year or author can be recovered securely.

By c. 300–500 CE: the version ancestral to the received
compendium was probably known to Dṛḍhabala, a redactor of the
Carakasaṃhitā. 1

Sixth century: the Bower Manuscript names Sushruta among
a group of medical sages; this is the earliest firm external link between
the name and the medical tradition. 1

Late eighth century: a later Arabic bibliography reports
that the physician-translator Mankah rendered a work called
Kitāb Susrud for the Barmakid patron Yaḥyā ibn Khālid.

878 CE: the palm-leaf manuscript Kathmandu KL 699 was
copied. It is the oldest securely dated surviving witness and often
preserves readings earlier than the standard printed text.

1907–1916: Kaviraj Kunja Lal Bhishagratna published a
three-volume English translation in Calcutta, making a later received
version widely accessible to English readers. 4

Since 2020: the Suśruta Project has used KL 699 and related
Nepalese manuscripts for a new edition, revealing substantial change
between the ninth-century recension and later printed versions.
