Great was his power and glorie ouer all,
2 Which him before, that sacred seate did fill,
That yet remaines his wide memoriall:
4 He dying left the fairest Tanaquill,
Him to succeede therein, by his last will:
6 Fairer and nobler liueth none this howre,
Ne like in grace, ne like in learned skill;
8 Therefore they Glorian call that glorious flowre,
Long mayst thou Glorian liue, in glory and great powre.

Tanaquil > (Historically, Caia Tanaquil, wife of Tarquinius Priscus, 5th King of Rome (- 577 BC); an exemplary queen, taken as the type for Gloriana as the Faery Queen. Hence, allegorically: Elizabeth, so that Oberon becomes identifiable with Henry VIII and Elficleos with Henry VII)
