Toroc

According to the Old English Dictionary:

toroc

a bung, stopper of a cask (?):--Toroc dolua, Wrt. ii. 141, 67. [From Latin (?) turachium epistomium, dolii obturamentum, Migne. Cf. (?), too, French douve stave of a cask. Another attempt at a meaning, however, may be suggested. Du Cange, who does not give dolua, gives toroc as a gloss for gurgulio; if this were the same word as that in the A. S. gloss, perhaps the latter is tó-roc; cf. ed-roc.] toroc
