      [W]hoso rhymes a sonnet pays a tax, / Who paints a landscape dips brush at his cost, / Who scores a septett true for strings and wind / Mulcted must be—else how should I impose / Properly, attitudinize aright, / Did such conflicting claims as these divert / Hohenstiel-Schwangau from observing me?
