Plate 1 of Andreas Cellarius's \u003cem\u003eHarmonia Macrocosmica\u003c\/em\u003e, printed from a copper plate in Amsterdam by Johannes Janssonius and coloured by hand.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eAn atlas of systems, not of stars.\u003c\/strong\u003e Cellarius did not set out to map the sky so much as to draw the competing pictures of it side by side — the earth-centred system of Ptolemy, the sun-centred one of Copernicus, the compromise of Tycho Brahe — each as a full-page plate, each argued in the same ornamental language. This is the first of them, and the oldest idea in the book.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat this is.\u003c\/strong\u003e A giclée reproduction printed with pigment inks from the Zentralbibliothek Zürich's own open-access scan of its copy, shelfmark T 12.

At that scale the printed border of the plate measures 51.34 × 43.75 cm on the Zurich copy. A second copy, in the Städtisches Museum Schloss Rheydt, is catalogued at 51.1 × 43.1 cm to the plate mark; hand-made paper moves by about one per cent from copy to copy, and the two agree within that.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat is cropped and what is not.\u003c\/strong\u003e The print stops at the outer printed rule of the engraving, the same convention we use for the block edge of a Japanese woodcut. The embossed plate mark lies about 2.5 mm outside that rule and stays out, as does the wide paper margin of the atlas leaf. The rule itself wanders by up to 3 mm across the width, because the leaf is bowed where it was bound; the crop takes the outer envelope of it, so a little paper comes in where the rule sits inside. Nothing is cut into the engraving. The engraved plate number 1 stands in the lower right corner and stays in the picture.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe fold.\u003c\/strong\u003e The plate was printed on a sheet wider than the book and folded once to be bound. The fold runs vertically down the middle of the picture, it is in the library's file, and it prints. We do not retouch it out. It is what a plate in a bound atlas looks like after three and a half centuries.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eOn the borders.\u003c\/strong\u003e The plate is wider than it is tall and the sheet is square, so the margins cannot be equal. On the small sheet the image takes the house width, 84 % of the sheet: 4.00 cm at each side, 6.61 above and 7.60 below. On the large sheet the plate is printed at its own size, which leaves 9.33 cm at the sides, 12.21 above and 14.04 below. Both sit at optical centre, 1:1.15, not in the middle.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhy there is no bigger sheet.\u003c\/strong\u003e Resolution is not the limit here. The scan carries 8085 pixels across the plate, which at our 300 dpi floor would cover an image 68 cm wide. The sheet is the limit: the plate's proportion, 1.17 to 1, sits between the shapes we stock, and the square sheet holds it with even side margins where the next larger sheets are long rectangles that would leave some 15 cm of paper at either side. So the large sheet prints the plate at its own size and stops there.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eProvenance\u003c\/strong\u003e\u003cbr\u003e\nAndreas Cellarius (c. 1596–1665), \u003cem\u003ePlanisphaerium Ptolemaicum, sive machina orbium mundi ex hypothesi Ptolemaica in plano disposita\u003c\/em\u003e, plate 1 of \u003cem\u003eHarmonia macrocosmica, seu Atlas universalis et novus\u003c\/em\u003e.\u003cbr\u003e\nAmsterdam: apud Joannem Janssonium, 1661.
