"He who was in advance: "Now help, Death, help!" And the other one, who seemed to lag too much, Was shouting: "Lano, were not so alert Those legs of thine at joustings of the Toppo!""

(Canto 13, lines 118-121)

"The other" is Giacomo Sant' Andrea, known in the poem as Iacopo. He was the son of Oderico da Monselice and Ezzolino III's former wife Speronella Delesmanini. In 1237 he followed Frederick II, but was killed by Ezzolino IV's men in 1239. He is notorious for having been a manic spender of money: one story about him tells that he once threw coins from a boat on the river Brenta to pass time, another that he set fire to his house to enjoy the sight of something burning.

"Lano's" real name might have been Ercolano Maconi or Arcolano da Squarcia di Riccolfo Maconi and is said to have been from Siena. His great wastefulness is mentioned by Boccaccio. Once a third estate representative of San Martino in Siena, after he had wasted his whole estate, he volunteered to become a soldier. He was killed by an enemy ambush in the battle of Pieve al Toppo fought between Siena and Arezzo - here ironically referred to as "joustings" by his companion.
