Summary

Description

Zodiac diagram: a matching diagram for H. P. Blavatsky's Scrapbooks, volume 11, page 71, item 1. The concentric months and zodiac figures, central sun and rays, small earth and intermediate bodies, and four numbered geometric corner symbols correspond to the album's diagram. The diagram has no individual printed title below it on the reviewed first page; Zodiac diagram is a descriptive label. The artist or engraver is not established.

Source publication: The Herald of Progress, volume II, no. 39, Friday, 8 April 1881, first page (one-based PDF page 1). The issue/date/volume are printed in the masthead. The album clipping includes the masthead; this source file isolates the diagram's native embedded scan plate. No separate printed folio is asserted. This identifies the exact matching issue, not the particular physical copy used in the scrapbook.

File and processing

Grayscale PNG, 4060 × 4196 pixels. Direct extraction and lossless decoding of the first PDF page's original JPEG 2000 image object 500 (/P1), DeviceGray, 670,046 bytes, SHA-256 13de1898826378beb9d3907114755c8d79ae15de1224a1165de0ccbd2bb9d635. Original PDF SHA-256 79926680b7f87c5f81373bd04451be81b6b54122941debb86569dd18c369a710.

The embedded image already separates the diagram from the journal masthead. Its complete native extent is retained, including all outer lines, corner symbols, labels, scan specks, white footer and Google digitization imprint. Printed boundaries are already aligned: no rotation, further crop, resizing or interpolation. Decoded pixels independently match the native PDF image returned by a second decoder. No enlargement, tonal adjustment, colourization, sharpening, retouching or reconstruction. Original PDF and JP2 bytes remain unchanged. Native pixel count is not a measurement of the source's optical resolving power. This is a monochrome witness, not a natural-paper-colour scan.
