There was a statue of Alberto in the hallway of Unseen University, inscribed (apart from the usual student scribbles) with ""We Shall Not See His Like Again"." This, of course, turns out to be entirely wrong. After the destruction of the statue in "Mort", and the wizards' belief that the returned Albert was the statue, it is suggested that a new one be built in a very secure place—such as the dungeon (allegedly to prevent it being defiled by students). Alberto Malich was a powerful wizard, perhaps the most powerful a wizard can be (though not likely a Sourcerer). This is reflected in how easily Albert devised a spell to slow the passage of time (a near-impossible feat with Discworld magic) indefinitely around a small area.
