Methodists were a self-identified medical sect of the 1st century
The Antikythera Mechanism (National Archaeological Museum, Athens, inv. X 15087) was a Hellenistic gearwork device for displaying astronomical and chronological functions. Substantial but highly corroded remains of the instrument were recovered from an ancient shipwreck (see Figure 1).
The most complex scientific instrument to have survived from antiquity, it resembled the sphaerae or planetaria described by Cicero (1) and other Greco-Roman authors. The date of its construction is in dispute but must have been earlier than the middle of the 1st century

The classical world witnessed many forms of landscape change in its physical geography, mostly due to longer-term geological and climatological processes, whilst only a minority were due purely to human action. The physical environment of Greek and Roman societies saw alterations through earthquakes, volcanic eruptions, sea-level fluctuations, erosion, and alluviation.
Already in Greek antiquity, Plato (Critias iii) observed how the Aegean physical landscape was being worn down over time as erosion from the uplands filled the lowland plains. Indeed, the Mediterranean region is amongst the most highly erodible in the world.1 However, scientific research in the field known as geoarchaeology has revealed a more complex picture than a continuous degradation of the ancient countryside.2
To uncover a more realistic picture of Mediterranean landscape change, the element of timescales proves to be central, and here the framework developed by the French historian Fernand Braudel3 provides the appropriate methodology. Braudel envisaged the Mediterranean past as created through the interaction of dynamic forces operating in parallel but on different “wavelengths” of time: the Short Term (observable within a human lifetime or less), the Medium Term (centuries or more, not clearly cognisant to contemporaries), and the Long Term (up to as much as thousands or millions of years, not at all in the awareness of past human agents).
Ancient peoples lived in close proximity to the environment and experienced at first hand natural phenomena and landscape features that, while often helpful or indeed essential to life, were also potentially threatening. The land and its produce were crucial to survival, and in a predominantly rural world dotted with towns and cities, many people will have observed at first hand mountains, rivers, and the relationship of landscape to available space for settlement. Rivers expressed the local community’s link with the landscape and sustained river valley communities by providing water for drinking, washing, irrigation, and watering of animals, as well as offering routes of communication. Many rivers were also a fruitful source of fish, especially if the water was clean, such as the high-quality fish from the Pamisos in Messenia (Paus. 4.34.1–2). But of course rivers could also flood a settlement or sweep it away. In addition, popular reaction to the environment around the local area was often influenced by strong cultural and religious feelings associated with landscape. In this context, it is not surprising that some literary works were exclusively devoted to natural features of the landscape, for example describing rivers, their character, history, and legendary associations. Mythology helped to explain natural phenomena. Furthermore, the theme of rivers in various guises appears repeatedly in the work of geographers, ethnographers, teachers, poets, and historians. Philosophers were also interested in the curiosities of riverine conditions, which, by their timeless quality yet constant movement, seemingly offered a comment on the human condition.
Glass came of age during the Roman period. Within the ancient world it had been used from the mid-second millennium
Vessels, windows and other items spread widely throughout the empire and beyond, and to all levels of society. Over the next 400 years, how the material was used changed with time and place as the various regional industries responded to the needs and preferences of their communities.
This was a major high-temperature industry which would have made considerable demands on resources such as fuel, but there are still many things that are unknown about it. Where, for example, was the glass itself made? Waste from secondary workshops producing vessels is regularly encountered, but evidence for the primary production is extremely rare. This has led to considerable debate, with competing models being proposed. Glass is not a material where scientific techniques such as those used to provenance pottery have proved very helpful. The composition of Roman glass is extremely uniform throughout the empire, and again there has been much debate about why this might be. Of late, some useful advances have started to be made in approaching these questions, and this may eventually disentangle what was going on.
The study of Roman glass provides a unique window into the past. Through it the impact of new technologies and materials can be seen, as well as the choices people made about what was useful in their lives—all against the background of some of the most beautiful and skilful vessels ever made.
