Chapter 16 of 16 · The great periods of history
The images in this volume
The four photographs in this volume, with their title at the source, their author, the address of their original page, their licence and the date on which it was checked.
What this chapter commits to
This volume serves four photographs. All of them are free: their licence was recorded on the image's original page, then checked again on the day the image entered this book. An image whose licence cannot be traced to its source does not enter, and there is no exemption. A chapter that teaches how to question its sources cannot serve images whose origin it would not state.
Three of these images carry the Creative Commons Zero dedication, which places the work as close as possible to the public domain; its text can be read at https://creativecommons.org/publicdomain/zero/1.0/. Two of them come from the open access programme of the Metropolitan Museum of Art, whose object record says Public Domain and whose image policy names the CC0 dedication. The fourth is under the Creative Commons Attribution 4.0 licence, which requires the author to be credited, and whose text can be read at https://creativecommons.org/licenses/by/4.0/; its author offers it under a choice of two licences, and it is that branch which this book keeps.
Each photograph has been cropped to the format of the page and recoloured in the colours of the house. That is a modification, the licence obliges us to say so, and every entry says so. The caption placed under an image therefore carries no attribution: it carries what the image teaches. The credit lives here, once, and once only.
