  1. Generated image, not a photograph. Based on one sentence of Strabo (Geography 17.1.8): the Museum is part of the palaces and has a public walk, a place furnished with seats and a large hall in which the men of learning of the Museum take their common meal. Strabo is describing the Museum. He does not mention the Library in this passage, and no remains of the Library have been recovered, so nothing here shows its rooms. The image shows a colonnade, a stepped seating recess and a stone hall with a door. The seating looks like a small theatre and the planters look modern. A tower-shaped shadow falls across the paving with no tower to cast it, and faint ghost columns show at the image edges. The distant pedimented buildings, columns, paving, colours, proportions, sea view and planting are guesses
    • The public walk

      Object, in an imagined view

      Strabo writes that the Museum is part of the palaces and has a public walk. The curved colonnade stands for that walk. The column style, the curve, the roof and the proportions are guesses.

      This view is imagined. The thing described is in the written record, and the source below says where.

      attested primary Source

    • Place with seats

      Object, in an imagined view

      Strabo also lists a place furnished with seats. He gives no size or look. The curved stone steps are invented and look more like a small theatre than anything he describes.

      This view is imagined. The thing described is in the written record, and the source below says where.

      attested primary Source

    • Door to the large hall

      Object, in an imagined view

      Strabo names a large hall in which the men of learning of the Museum take their common meal. He does not say where it stood or what it looked like. The stone block and its doorway are a guess.

      This view is imagined. The thing described is in the written record, and the source below says where.

      attested primary Source

    • Sea and gardens

      Object, in an imagined view

      Sea, palms, cypresses and distant pedimented buildings beyond the walk. Strabo's sentence gives no view. They are invented.

      This view is imagined. The thing described is a guess. No source records it for this library.

      invented primary Source

    • Paving

      Object, in an imagined view

      Stone slabs. Nothing is recorded of the surface. A tower-shaped shadow falls across them to one side, and no building in the image casts it.

      This view is imagined. The thing described is a guess. No source records it for this library.

      invented primary Source
