Leviodanum

AttestedLeviodanum at position 220 in the Ravenna Cosmography

Where:  The Bertha Roman fort at NO097268, where the river Almond flows into the Tay north of Perth.  It was named relatively recently as Bertha and lies across the Tay from Scone, the traditional site of coronation of Scottish kings, which was probably ancient Ταμεια ‘Tay crossing’.

Name origin:  The ending –danum resembles *danu, which contributed to the names of rivers across the ancient world that were somehow double, including two instances of Dano in Britain, and various rivers now called Don, including one not far away at Aberdeen.   Initial Levio- is a longstanding problem.  The best guess now is to regard Leviodanum as closely associated with Levioaxava (Perth, ‘the lips of the Tay’), thereby downgrading the possible parallels with levee ‘embankment’, or with Latin levo ‘to elevate’, levo ‘to smoothe’, or Laevus ‘left’.  Or with the element Lav- discussed here as possibly associated with variable rivers.  What tips the balance is that Levefanum is now thought to be at Arnhem-Meinerswijk (not far from the famous Bridge Too Far), rather than at Wijk bij Duurstede (where Roman timber river-edging has been found).  Also Durolevo in Kent shows the same sort of lips-of-river topography.

NotesCrawford (1949:60-61) recognised Derder's Ford between Bertha and Scone as the remains of a former weir just downstream from a bridge that was probably originally Roman.  (Although the Tay is Britain’s biggest river in terms of flow rate, during a hot, dry spell its depth of water at Perth can drop to an easily fordable trickle.)  The diagram below, copied from Selkirk (1995 p259), shows the fort F, bridge B, and weir W in close proximity near the tidal limit of the Tay.  Unfortunately, Raymond Selkirk is a hate figure for many archaeologists, who choose to ignore his clear explanation (pages 241-248) of the river engineering involved.  So there has been no mature discussion of whether there were originally two separate weirs, or just “one curved weir that served to deepen both rivers”.  Is it pure coincidence that Derder's Ford looks like Duro- ‘crossing’ twice over?
