How do the references to ideas on horseback and long haired virtues fit into the overall structure of the poem?

Part I

1On either side the river lie

2Long fields of barley and of rye,

3That clothe the wold and meet the sky;

4And thro' the field the road runs by

5       To many-tower'd Camelot;

6And up and down the people go,

7Gazing where the lilies blow

8Round an island there below,

9       The island of Shalott.

10Willows whiten, aspens quiver,

11Little breezes dusk and shiver

12Thro' the wave that runs for ever

13By the island in the river

14       Flowing down to Camelot.

15Four gray walls, and four gray towers,

16Overlook a space of flowers,

17And the silent isle imbowers

18       The Lady of Shalott.

19By the margin, willow veil'd,

20Slide the heavy barges trail'd

21By slow horses; and unhail'd

22The shallop flitteth silken-sail'd

23       Skimming down to Camelot:

24But who hath seen her wave her hand?

25Or at the casement seen her stand?

26Or is she known in all the land,

27       The Lady of Shalott?

28Only reapers, reaping early

29In among the bearded barley,

30Hear a song that echoes cheerly

31From the river winding clearly,

32       Down to tower'd Camelot:

33And by the moon the reaper weary,

34Piling sheaves in uplands airy,

35Listening, whispers " 'Tis the fairy

36       Lady of Shalott."

Part II

37There she weaves by night and day

38A magic web with colours gay.

39She has heard a whisper say,

40A curse is on her if she stay

41       To look down to Camelot.

42She knows not what the curse may be,

43And so she weaveth steadily,

44And little other care hath she,

45       The Lady of Shalott.

46And moving thro' a mirror clear

47That hangs before her all the year,

48Shadows of the world appear.

49There she sees the highway near

50       Winding down to Camelot:

51There the river eddy whirls,

52And there the surly village-churls,

53And the red cloaks of market girls,

54       Pass onward from Shalott.

55Sometimes a troop of damsels glad,

56An abbot on an ambling pad,

57Sometimes a curly shepherd-lad,

58Or long-hair'd page in crimson clad,

59       Goes by to tower'd Camelot;

60And sometimes thro' the mirror blue

61The knights come riding two and two:

62She hath no loyal knight and true,

63       The Lady of Shalott.

64But in her web she still delights

65To weave the mirror's magic sights,

66For often thro' the silent nights

67A funeral, with plumes and lights

68       And music, went to Camelot:

69Or when the moon was overhead,

70Came two young lovers lately wed:

71"I am half sick of shadows," said

72       The Lady of Shalott.

Part III

73A bow-shot from her bower-eaves,

74He rode between the barley-sheaves,

75The sun came dazzling thro' the leaves,

76And flamed upon the brazen greaves

77       Of bold Sir Lancelot.

78A red-cross knight for ever kneel'd

79To a lady in his shield,

80That sparkled on the yellow field,

81       Beside remote Shalott.

82The gemmy bridle glitter'd free,

83Like to some branch of stars we see

84Hung in the golden Galaxy.

85The bridle bells rang merrily

86       As he rode down to Camelot:

87And from his blazon'd baldric slung

88A mighty silver bugle hung,

89And as he rode his armour rung,

90       Beside remote Shalott.

91All in the blue unclouded weather

92Thick-jewell'd shone the saddle-leather,

93The helmet and the helmet-feather

94Burn'd like one burning flame together,

95       As he rode down to Camelot.

96As often thro' the purple night,

97Below the starry clusters bright,

98Some bearded meteor, trailing light,

99       Moves over still Shalott.

100His broad clear brow in sunlight glow'd;

101On burnish'd hooves his war-horse trode;

102From underneath his helmet flow'd

103His coal-black curls as on he rode,

104       As he rode down to Camelot.

105From the bank and from the river

106He flash'd into the crystal mirror,

107"Tirra lirra," by the river

108       Sang Sir Lancelot.

109She left the web, she left the loom,

110She made three paces thro' the room,

111She saw the water-lily bloom,

112She saw the helmet and the plume,

113       She look'd down to Camelot.

114Out flew the web and floated wide;

115The mirror crack'd from side to side;

116"The curse is come upon me," cried

117       The Lady of Shalott.

Part IV

118In the stormy east-wind straining,

119The pale yellow woods were waning,

120The broad stream in his banks complaining,

121Heavily the low sky raining

122       Over tower'd Camelot;

123Down she came and found a boat

124Beneath a willow left afloat,

125And round about the prow she wrote

126       The Lady of Shalott.

127And down the river's dim expanse

128Like some bold seër in a trance,

129Seeing all his own mischance—

130With a glassy countenance

131       Did she look to Camelot.

132And at the closing of the day

133She loosed the chain, and down she lay;

134The broad stream bore her far away,

135       The Lady of Shalott.

136Lying, robed in snowy white

137That loosely flew to left and right—

138The leaves upon her falling light—

139Thro' the noises of the night

140       She floated down to Camelot:

141And as the boat-head wound along

142The willowy hills and fields among,

143They heard her singing her last song,

144       The Lady of Shalott.

145Heard a carol, mournful, holy,

146Chanted loudly, chanted lowly,

147Till her blood was frozen slowly,

148And her eyes were darken'd wholly,

149       Turn'd to tower'd Camelot.

150For ere she reach'd upon the tide

151The first house by the water-side,

152Singing in her song she died,

153       The Lady of Shalott.

154Under tower and balcony,

155By garden-wall and gallery,

156A gleaming shape she floated by,

157Dead-pale between the houses high,

158       Silent into Camelot.

159Out upon the wharfs they came,

160Knight and burgher, lord and dame,

161And round the prow they read her name,

162       The Lady of Shalott.

163Who is this? and what is here?

164And in the lighted palace near

165Died the sound of royal cheer;

166And they cross'd themselves for fear,

167       All the knights at Camelot:

168But Lancelot mused a little space;

169He said, "She has a lovely face;

170God in his mercy lend her grace,

171       The Lady of Shalott."
