Logos follows the direct method of language learning, refraining from using languages other than Ancient Greek in its lessons. A big differential of this book is how simple it starts, introducing new vocabulary and grammatical concepts very slowly in its first chapters. In the first few chapters, most of the vocabulary can be somewhat easily understood by the glosses on the margins of the pages or by context. However, as you proceed through the chapters, the book does pick up the pace and more frequent visits to a dictionary will be necessary. That said, the book also does a very good job of not leaving vocabulary behind, it consistently works spaced repetition within its texts. Every once in a while you will also find chapters composed entirely with vocabulary you have already learned, making for a very satisfying reading experience.

The vocabulary in Geoffrey's texts is organized in such a way that the core vocabulary, which is repeated more often through the text, is presented to be memorized before reading the text itself and the less common vocabulary is found on the facing pages of each section, alongside the rich commentary. The collection of texts includes, among others, select books from the Odyssey and Illiad as well as several of Plato's Dialogues.

Based on W.H.D. Rouse's 1909 A Greek Boy at Home, Alexandros adapts Rouse's story and adds to it exercises and glosses inspired by the Lingua Latina method.
Supplementary material

A companion to Alexandros divided in two parts. The first one presents stories on the Olympian gods, the second one retells famous Greek myths. Stories include Jason and the Golden Fleece, Theseus and the Minotaur, Arachne and Athena, Perseus and Medusa, Orpheus and Eurydice, Apollo and Daphne, and Odysseus with the Trojan Horse.

The book tells the story of newborn Hermes who wishes to steal all sorts of things. The events in the story are based on Lucian's Dialogues of the Gods as well as the Homeric Hymn to Hermes. The glossary provided is very robust and contains both entries on individual words and on full sentences for harders constructions. The author makes very good use of a relatively small vocabulary of 87 unique words to make the story easy to follow even for beginners, making for very good practice of naturally understanding declensions and conjugations.

Not didactic readers, per se, but a few of Asterix’s adventures have been translated into Attic Greek. Sadly, such editions are not readily available nowadays as they are published as limited collector's items rather than preserved for posterity.

A very powerful dictionary search tool which aggregates entries of several dictionaries, such as LSJ, Brill-Montanary, Bailly, etc as well as providing corpus data from Perseus Project. Very easy to use and contains useful study tools such as reverse lookup and morphological analysis tools.
