"My subject is a barren one – the world of nature, or in other words life; and that subject in its least elevated department, and employing either rustic terms or foreign, nay barbarian words that actually have to be introduced with an apology. Moreover, the path is not a beaten highway of authorship, nor one in which the mind is eager to range: there is not one of us who has made the same venture, nor yet one Roman who has tackled single-handed all departments of the subject."Naturalis Historia was written by Pliny the Elder between 77 and 79 CE and was meant to serve as a kind of proto-encyclopedia discussing all of the ancient knowledge available to him, covered in enough depth and breadth to make it by a reasonable margin the largest work to survive to the modern day from the Roman era. The work includes discussions on astronomy, meteorology, geography, mineralogy, zoology and botany organized along Aristotelian divisions of nature but also includes essays on human inventions and institutions. It is dedicated to the Emperor Titus in its epistle to the Emperor Vespasian, a close friend of Pliny who relied on his extensive knowledge, and its unusually careful citations of sources as well as its index makes it a precursor to modern scholarly works. It was Pliny's last work, as well as sadly his sole surviving one, and was published not long before his death attempting to save a friend from the eruption of Mt. Vesuvius that destroyed Pompeii and Herculaneum, famously recounted by Pliny's eponymous nephew Pliny the Younger.

The Seljuk Han in Anatolia has tons of information about and pictures of the caravanserai, inns for caravans, built by the Seljuk Sultanate of Rûm in what is now Turkey. The Seljuk caravanserai, called hans, were a vital resource for trade from the middle ages to recent times. The website, by Katherine Branning, explains what a han is, their origins, their function in trade, what life there was like and much more. The site also features 39 individual hans, such as the Kadin Han, now a furniture store, Dibi Delik Han, which is undergoing restoration, Zazadin Han, which has been restored already, and the spectacular Sultan Han Kayseri. For an academic survey of Seljuk hans, here's Ayşıl Tükel Yavuz' The concepts that shape Anatolian Seljuq caravanserais [pdf, automatic download].
