at a whistle’s sound. 
    Ah, how much in my mind was I disturbed,
      When I turned round to look on Beatrice,
      At not beholding her, although I was
    Close at her side and in the Happy World!

[Line 1:  This “Divina Commedia,” in which human science or Philosophy is symbolized in Virgil, and divine science or Theology in Beatrice.

“Fiorenza la Bella,” Florence the Fair.  In one of his Canzoni, Dante says,—­

    “O mountain-song of mine, thou goest thy way;
    Florence my town thou shalt perchance behold,
    Which bars me from itself,
    Devoid of love and naked of compassion.”]

[Line 9:  This allusion to the Church of San Giovanni, “il mio bel San Giovanni,” as Dante calls it elsewhere, (Inf. xix. 17,) is a fitting prelude to the Canto in which St. John is to appear.  Like the “laughing of the grass” in Canto xxx. 77, it is a “foreshadowing preface,” ombrifero prefazio, of what follows.

See Canto xxiv. 150;

    “So, giving me its benediction, singing,
      Three times encircled me, when I was silent,
      The apostolic light.”]

[Line 30:  The General Epistle of St. James, called the Epistola Cattolica, i. 17.  “Every good gift and every perfect gift is from above, and cometh down from the Father of lights.”  Our Basilica:  Paradise:  the Church Triumphant.]

[Line 33:  Peter, James, and John, representing the three theological virtues, Faith, Hope, and Charity, and distinguished above the other apostles by clearer manifestations of their Master’s favor.]

[Line 34:  St. James speaks.]

[Line 37:  The three Apostles, luminous above him, overwhelming him with light.]

[Line 38:  “I will lift up mine eyes unto the hills, from whence cometh my help.”  Psalm cxxi. 1.]

[Line 42:  The most august spirits of the Celestial City.]

[Line 49:  Beatrice.]

    “Where everything beholds itself depicted.”

[Line 56:  To come from earth to heaven.]

[Line 58:  “Say what it is,” and “whence it came to thee.”]
