This chapter presents new, annotated translations of various surviving works by Markianos of Herakleia, who is probably the man of that name who lectured at Constantinople just before and just after AD 400. The chapter introduction shows that it is to him that we owe one of the two collections of geographical works that survive from antiquity (perhaps built on foundations laid by Menippos); its sole surviving copy, though incomplete, includes several works translated in the present volume. The main work presented here is the partly extant abridgement of Markianos’ Circumnavigation of the Outer Ocean, dealing first (book 1) with the lands from eastern Africa to western China, and then (book 2) with the coasts of the northern Atlantic. To this are appended over 40 citations of Markianos by Stephanos of Byzantion and others, as well as the theoretical opening sections of Markianos’ epitome (précis) of Menippos (the whole epitome is in Chapter 21 of this volume). His perceptive preface to Ps.-Skylax is printed in Chapter 7. At many points, such as when discussing how to present distances that display systematic errors, he shows himself to be one of the most self-aware and methodologically astute of ancient writers, as well as exceptionally widely read. New maps explain his presentation of the Far East and northern Europe.

This chapter presents a new, annotated translation of the anonymous, but substantial, Hypotypōsis (Outline) of Geography which, like the shorter outline by Agathemeros (Chapter 29 of this volume), was probably written as a new preface to Arrian’s collection of geographical works; it is thought to date from the last third of the 6th century AD and may be by the same author as the Circumnavigation of the Euxine (Chapter 36). The author begins with general principles about the Earth and the continents, before surveying the regions of the oikoumene (inhabited portion of the Earth) systematically, then the ‘gulfs’ of the outer Ocean. After a discussion of the wind rose, the dimensions of the principal seas are given, followed by the climatic zones and details of Lake Maiotis (the Sea of Azov). The chapter introduction shows that the text represents an expansion and update of Agathemeros, incorporating a Ptolemaic understanding of the world.

This chapter presents a new, annotated translation of the short Hypotypōsis (Outline) of Geography by one Agathemeros son of Orthon, written around AD 125–50, probably as a new preface to Arrian’s collection of geographical works (like the later Hypotypōsis in Chapter 35). The chapter introduction identifies its value as a summative account of hellenistic views of geography, showing as yet no influence from Ptolemy and citing no sources later than Poseidonios. The work outlines the succession of geographers, different versions of the wind rose, and the main parts of the inhabited world and its dimensions, and closes with a catalogue of islands. It is important as a source of information about Artemidoros and other earlier writers.
