There was no great disparity of years, Though much in temper; but they never clash'd, They moved like stars united in their spheres, Or like the Rhône by Leman's waters wash'd, Where mingled and yet separate appears The river from the lake, all bluely dash'd Through the serene and placid glassy deep, Which fain would lull its river-child to sleep.

What It Means

This is a placeholder explanation generated by the low-overhead model. It interprets "There was no great disparity of years, Though much in temper; but they never clash'd, They moved like stars united in their spheres, Or like the Rhône by Leman's waters wash'd, Where mingled and yet separate appears The river from the lake, all bluely dash'd Through the serene and placid glassy deep, Which fain would lull its river-child to sleep." in the context of "Lord Byron, Don Juan (1818-24), Canto XIV, Stanza 87." to mean that wisdom is timeless.
