Root / Etymology

From θύρα (thýra, 'door'), referring to the shield's door-like shape and size.

Historical & Contextual Notes

In classical Greek, θυρεός refers primarily to the large, oblong shield used by Greek and later Roman heavy infantry (notably the scutum). The name's derivation from 'door' alludes to both its shape and its function as a barrier. This type of shield was especially associated with formations that required overlapping shields for maximum defense. In the Septuagint and New Testament, θυρεός continues to denote the large shield as distinct from smaller, round shields (ἀσπίς). Its use in Ephesians 6:16 for 'shield of faith' reflects this imagery of comprehensive protection. Whereas English translations typically render it as 'shield,' the specific connotation of size and coverage is not always apparent; other Greek words like ἀσπίς (aspís) and πυρίον (puríon) refer to smaller or different-shaped shields.

Original Strong's Gloss (1890)

from θύρα; a large shield (as door-shaped):--shield.
