What ᛮ means
It marks golden number 17 in a runic calendar.
That number also helps calculate movable Christian feast dates.
The 1328 Gotland calendar records it; runic calendars also appear on Northern European wooden staves and parchment.
Why is Arlaug linked to Tvimadur and Belgthor?
They complete the cycle’s final three numbers.
The 16-letter Younger Futhark rune alphabet left three gaps: Arlaug marks 17, Tvimadur ᛯ marks 18, and Belgthor ᛰ marks 19. Ole Worm recorded all three in 1636.
