Note 32-2 — THE SAGA OF ERIC THE RED
Reading edition
Dœgr was a period of twelve hours. Reeves quotes the following from an old Icelandic work: “In the day there are two dœgr; in the dœgr twelve hours.” A dœgr’s sailing is estimated to have been about one hundred miles. There is evidently a clerical error in this passage after the number of days’ sailing. The words for “two” and “seven” are very similar in old Norse.
