Note 55 — Chapter IV
Reading edition
Lazzerini, in his Memorie Storiche dei Conti di Urbino, has discussed without exhausting them in fifty folio pages. The magnificent work by Count Pompeo Litta is marred by adopting the theory of an Ubaldini descent for Duke Federigo. See his notice of Emilia Pio da Carpi, wife of Count Antonio di Montefeltro.
