104.29

Most wretched wight, whom nothing might suffise,
2 Whose greedy lust did lacke in greatest store,
Whose need had end, but no end couetise,
4 Whose wealth was want, whose plenty made him pore,
Who had enough, yet wished +euer more+;
6 A vile disease, and eke in foote and hand
A grieuous gout tormented him full sore,
8 That well he could not touch, nor go, nor stand:
Such one was Auarice, the +fourth+ of this faire band.
