Tempore difficiles veniunt ad aratra juvenci;
Tempore lenta pati frena docentur equi.
In time the unmanageable young oxen come to the plough; in time the horses are taught to endure the restraining bit.
The raven once in snowy plumes was drest,
White as the whitest dove's unsullied breast,
Fair as the guardian of the Capitol,
Soft as the swan; a large and lovely fowl
His tongue, his prating tongue had changed him quite
To sooty blackness from the purest white.
