Herbert's date of death has been the source of confusion. The date 5 August appears in the burial registers of St Giles in the Fields, and is corroborated by independent documentary evidence. However, his tombstone, erected some years later, apparently bore the date 20 August, and this date was subsequently accepted by many biographers. It is now believed to have been an error: see Roberts, Dunstan (2016). «The death of Lord Herbert of Cherbury revisited». Notes and Queries. 63 (1): 44–45. doi:10.1093/notesj/gjv228
