Forms
fētiālis m (genitive fētiālis); third declension[1][2] As an adjective: fētiālis (neuter fētiāle); third-declension two-termination adjective.[1][2] Manuscripts often spell it faet-.[2]
Etymology
It is inherited from Proto-Italic *fēti-āli-, a noun use of an adjective meaning “of the (religious) congregation”, formed with -ālis.[3][1] Its base *fētis goes back to Proto-Indo-European *dʰeh₁-ti- (“the putting, making”), a noun of *dʰeh₁- (“to put”).[3][1] De Vaan explains the sense as a development from “placement” to “prescription, law” and then to “body of priests”;[3] the OLD, more cautiously, sees “ordinance” in it.[2] Cognate with Ancient Greek θέσις (thésis, “setting, position”), Lithuanian dė́tis (“load”), Old Norse dáð (“deed”) and Old High German tāt (“deed”).[3][1]
Varro connected the fetials with fidēs1 (“faith”), because they watched over public good faith between peoples, in his work on the Latin language (5.86).[4]
Earliest recorded meaning
De Vaan dates it from Varro,[3] Köbler from Cicero;[5] in the laws of Cicero's De legibus the fetials are to be the judges of treaties, peace and war (foederum pacis, belli … fetiales iudices sunto).[6]
Semantic evolution
The fetials were a college of twenty priests who represented the Roman people in its dealings with other nations: they made treaties and truces sacred, demanded redress from peoples who had wronged Rome, and declared a war just only when redress was refused.[7][2][3] Those sent out as envoys were called fetiales legati, and in the singular Livy writes legatus fetialis.[7][8]
As an adjective it qualifies their law (ius fetiale, Cicero),[8][7] their ceremonies (caerimoniae, Livy)[8][7] and, in Arnobius, their rights (iura).[7] Apuleius also uses the adjective.[6]
