When Alfredo describes the Basilica of San Clemente as a building that has been constructed atop multiple “layers” of history, he draws a parallel between the passage of time and the nature of love. Insisting that “there is no first anything” and “no last anything,” he suggests that love, like time, is composed of many different histories. Thinking of love in this way is helpful when considering Elio and Oliver’s relationship, as the idea implies that although their bond may fade into the past, it will never vanish. Instead, it will inform all the other relationships that are “built” upon it, forming “secret passageways and interlocking chambers” that recall Mr. Pearlman’s idea of the human heart as something that consists of many “bends,” “chambers,” and “tollbooths.”
