the vorticies of cultures past and present

In Tales of the Tarsands (Dorothy Dahlgreen, 1975, Alberta: a Jean Publication) Marshall wrote in the back:

users of env =
effic[ient] cause
ovid’s met[amorphoses] as tales of
the vorticies of cultures
past and present

On the cover Marshall had written “from George Hendry”
