This paper is a reassessment of the use of the use of Dioptra 35 for the purposes of dating the activity of Heron of Alexandra. It is argued that the text does not contain a carefully recorded eclipse observation that can be attributed to Heron. The most that can be said is that the lunar eclipse of 13 March 62 can probably be taken as a terminus post quem for Heron's activity.
