In Greek mythology, Clytius (Ancient Greek Κλυτίος) is one of the earthborn Giants who assault Olympus in the Gigantomachy. Apollodorus records that Hecate killed him with torches.

I.Slain by Hecate
Apollodorus (Bibliotheca 1.6.2) names Clytius among the Giants destroyed when the Olympians fought with Heracles at their side: Hecate kills him with torches. The collective gigantes node holds the earthborn revolt; this node is the individual named in that battle roster.
Vase-painting and later art often show torch-bearing Hecate against a Giant without always labelling him Clytius; the literary pin remains Apollodorus.
II.Homonym care
The atlas id clytius-giant is the Gigantomachy Giant alone. Distinct from Clytius son of Eurytus (Argonaut / Oechalian), Priam's elder brother Clytius, the many suitor Clytii, and other namesakes on the Wikipedia disambiguation list.
