Karl Wilhelm Ludwig Müller in the context of Didot family

The Stadiasmus Maris Magni or Stadiasmus sive Periplus Maris Magni (Ancient Greek: Σταδιασμός ήτοι περίπλους της μεγάλης θαλάσσης) is an ancient Roman periplus or guidebook detailing the ports sailors encounter on the shores of the Mediterranean Sea. The stadiasmus provides distances, sailing directions and descriptions of specific ports. It was written in Ancient Greek and survives in fragments. The work was written by an anonymous author and is dated to the second half of the third century AD. The most complete Greek text together with a Latin translation was published in 1855 by Karl Müller as part of his work Geographi Graeci Minores.

Die Fragmente der griechischen Historiker, commonly abbreviated FGrHist or FGrH (Fragments of the Greek Historians), is a collection by Felix Jacoby of the works of those ancient Greek historians whose works have been lost, but of which we have citations, extracts or summaries. It is mainly founded on Karl Wilhelm Ludwig Müller's previous Fragmenta Historicorum Graecorum (1841–1870).

The work was started in 1923 and continued by him till his death in 1959. The project was divided into six parts, of which only the first three were published. The first included the mythographers and the most ancient historians (authors 1-63); the second, the historians proper (authors 64–261); the third, the autobiographies, local histories and works on foreign countries (authors 262-856). Parts I-III come to fifteen volumes, but Jacoby never got to write part IV (biography and antiquarian literature) and V (historical geography). A pool of editors is currently trying to complete this task (Die Fragmente der griechischen Historiker. Continued); 200+ new entries have been published online so far (in English, German, French and Italian), with editions in print following for part IV. Meanwhile a new English-language edition of Jacoby's original work (parts I-III) has also been published online, Brill's New Jacoby (BNJ), with a completely new commentary, providing English translations of all fragments and an updated bibliography.
