SOURCES

The sources of these pages

The historical and documentary statements on these pages rest on the sources listed below, and where the sources are weak or discordant the page says so instead of choosing the more evocative version. Some incidental details remain without a precise reference; they carry no argument of the project and can be recognised because no conclusion rests on them.

Islamic and Norman Sicily

Al-Andalus and the Corral del Carbon

Water, climate and techniques

Lexicon and rural architecture

Arabic texts quoted

In the pages the captions of these quotations give the author and the work and stop there. The qualification that applies to all of them is here: the vocalisation of the Arabic texts is reconstructed, it does not come from the sources that transmit them, and it awaits review by an Arabist. The two passages of al-Bukhari, 2072, are the exception, their vocalisation coming from the source. Ibn Jubayr and al-Idrisi appear only in Italian, because the Arabic text could not be verified.

What does not appear on these pages

Four claims that often circulate on these subjects were checked and discarded: that the daily temperature range of the Ragusa district is comparable to that of Fez, that the scirocco chambers date from the Islamic period, that the maiolica of Caltagirone is the Sicilian half of zellij, and that the ventilation system of the Zisa can be reconstructed in the details that circulate about it. None of them appears here.

Nor do quantitative measurements appear of the temperature reduction obtained from basins, sheets of water or Andalusian courtyards, because none is published by institutional sources.
