- 1663, Hudibras, by Samuel Butler, part 1, canto 1
  Quoth Hudibras, I smell a rat; \\ Ralpho, thou dost prevaricate: \\ For though the thesis which thou lay'st \\ Be true, ad amussim, as thou say'st; \\ For that bear-baiting should appear, \\ Jure divino, lawfuller \\ Than synods are, thou dost deny \\ Totidem verbis; so do I: \\ Yet there's a fallacy in this; \\ For if by sly homœosis, \\ Thou wouldst sophistically imply \\ Both are unlawful, I deny.
