It is often repeated that at the unsuccessful productions of Terence's Hecyra the audience left the theatre in order to see, on the first occasion, boxers and a tight-rope walker, on the second, a gladiatorial contest.1 The other view, that the spectators remained but demanded other entertainment, is to my mind clearly correct and deserves restatement since the mistaken one is so widespread.

Plutarch's dialogue De facie in orbe lunae contains a mention of an eclipse, the identification of which would give a terminus post quern, for the composition of the work. The speaker is the Etruscan Lucius, the Pythagorean friend of Sulla the Carthaginian, and his words are as follows : ‘Concede me this, remembering this recent eclipse, which, beginning immediately after midday , caused many stars to appear in many quarters of the sky.’ For such a phenomenon to occur the eclipse (...) must have been nearly or quite total.

This article comments on some of Professor Huang’s theses by looking at ancient historiography. It deals with the significance of history in its respective cultural contexts; the kind of orientation that historical thinking and historiography provide; and the relationship between concrete examples and abstract rules in historical argumentation. Distinguishing between ancient Greece and Rome, it shows that Huang’s explicit and implicit East–West oppositions are more valid with respect to ancient Greece than to ancient Rome. On important points, the situation of (...) Rome is surprisingly close to that of China. Thus not only in China but also in Rome, tradition and history are highly important as a life-orienting force ; and not only in China but also in Rome the orientation that historical thinking and historiography provide is to a great extent moral . As to the relationship between concrete examples and abstract rules in historical argumentation, the paper takes up Professor Rüsen’s category of “exemplary meaning-generation,” but suggests a distinction between example in the sense of “case/instance” and example in the sense of “model/paragon.” Though the two corresponding modes of exemplary meaning-generation are mostly entwined, it appears that in Chinese and Roman historical works there is a tendency toward meaning-generation by example in the sense of “model/paragon,” whereas in Greek historiography the tendency is toward meaning-generation by example in the sense of “case/instance.”.

After yeast cells commit to the cell cycle in a process called START, genes required for DNA synthesis are expressed in late G1. Periodicity is mediated by a hexameric sequence, known as a MCB element, present in all DNA synthesis gene promoters. A complex that specifically binds MCBs has been identified. One polypeptide in the MCB complex is Swi6, a transcription factor that together with Swi4 also binds G1 cyclin promoters and participates in a positive feedback loop at START. The (...) finding that Swi6 is directly involved in both START and DNA synthesis gene control suggest a model in which Swi6, activated through its participation in START, serves as the central transcription factor in coordinating late G1 gene expression. The mechanism may be conserved in all eukaryotic cells. (shrink)

Cynthia will leave Rome for the country: how fortunate that there will be no one there to seduce her—provided there is no visitor from the outside world! Propertius will himself go hunting. If Cynthia has any temptations, let her remember that in a few days he will be with her.
