Odysseus shows to Laertes his tell-tale scar, O.24.331, after the father asks his son for a sēma ‘sign, signal’ as proof of identity. Odysseus then also proves that he knows every detail about the Garden of Laertes, O.24.336–346. These sēmata ‘signs, signals’, O.24.346, are now recognized by Laertes, and the verb that signals such recognition is once again gignōskein ‘recognize’.
