A treatise on rhetorical tropes is attributed in manuscripts to the first-century grammarian Trypho: this article considers for the first time a fifteenth-century manuscript of this work (Leiden, BPG 74G), which turns out to be the only complete witness of its hitherto unknown original version; this version (very fragmentarily transmitted by a fifth-century papyrus scrap) is also partly found in another fifteenth-century manuscript now kept in Olomouc (M 79). Four interesting poetic fragments are quoted in this newly discovered, fuller version (...) of Ps.-Trypho'sDe Tropis: some lines from Callimachus’ fifth and fourthIambi(23–9 and 90–2 respectively: a radically new light is shed by this new witness on the parallel papyrus fragments carrying Callimachus’ text), an epigram dubiously attributed to Simonides (FGE44 Page, probably to be dated to the Hellenistic period: the text can be now restored to its complete form), and some enigmatic lines of “Hesiod”'sWedding of Keyx, which the new witness finally makes fully understandable.

Situated in critiques of the “moral muteness” of technical rationality, we examine concepts of ethics and the avoidance of ethical language among Australian gas pipeline engineers. We identify the domains in which they saw ethics as operating, including public safety, environmental protection, sustainability, commercial probity, and modern slavery. Particularly with respect to ethical matters that bear on public safety, in the course of design and operational activities, engineers principally advocated for action using technical language, avoiding reference to potential consequences such (...) as death or destruction of property. Within their organizations, they saw themselves as occupying a technical “line of defense”. We argue that this focus on technical language is action-oriented. Ethics tells practitioners of unacceptable outcomes, but it does not guide them in what they need to do to avoid that outcome in practice. We observed some cases where engineers had not made the connection between their role and ethics in the sense of public safety. We argue that muteness on ethical matters can obscure the nature of the risk where technical advice is being taken on by non-technical actors, and where technical actors themselves do not have a clear sense of their public safety obligations.
