No information is given about the date or context of this series. A clue of the date is at the beginning of the first lecture, in which Dunbar mentions the recent death of a Bahá'í. This appears to be Kent Beveridge, who perished in a scuba diving incident at Sharm El Sheikh, Egypt, on April 2, 1989 and was buried in the the cemetery at Eilat, Israel.
