“…Masià Dioptra 35 (Schöne 1903), pointing out that other eclipses fit the data of the eclipse there described (for a summary of these positions see Acerbi 2007). Recently, Sidoli corrected his last conclusion, recognizing that the only eclipse partially consistent with the data of Dioptra 35, in the five centuries between second century bc and third century ad, is the one identified by Neugebauer (Sidoli 2011). Contrary to Drachman's claim, Sidoli only regards this date as a terminus post quem for the dating of Hero.…”

The dating of Hero of Alexandria has been linked with the lunar eclipse of March 13, ad 62, since Otto Neugebauer discovered that this eclipse is the only one that can fit the one described in Hero's Dioptra 35. Although only a number of scholars claim that Hero himself observed the eclipse, almost all of them take Neugebauer's identification for granted. We use statistical and linguistic methods to criticize this assumption: all indices we have found point to the fact that the eclipse was merely invented as an example and, for that reason, that it cannot be used to determine Hero's life span.

Context. High-mass X-ray binaries (HMXBs) are a particular class of high-energy sources that require multi-wavelength observational efforts to be properly characterised. New identifications and the refinement of previous measurements are regularly published in the literature by independent teams of researchers and might, when they are collected in a catalogue, offer a tool for facilitating further studies of HMXBs. Aims. We update previous instances of HMXB catalogues in the Galaxy and provide the community easy access to the most complete set of observables on Galactic HMXBs. In addition to the fixed version that is available in Vizier, we also aim to host and maintain a dynamic version that can be updated upon request from users. Any modification will be logged in this version. Methods. Using previous HMXB catalogues supplemented by listings of hard X-ray sources detected in the past 20 years, we produced a base set of HMXBs and candidates by means of identifier and sky coordinate cross matches. We queried in Simbad for unreferenced HMXBs. We searched for as many hard X-ray, soft X-ray, optical, and infrared counterparts to the HMXBs as we could in well-known catalogues and compiled their coordinates. Each HMXB was subjected to a meticulous search in the literature to find relevant measurements and the original reference. Results. We provide a catalogue of 152 HMXBs in the Galaxy with their best known coordinates, the spectral type of the companion star, systemic radial velocities, component masses, orbital period, eccentricity, and spin period when available. We also provide the coordinates and identifiers for each counterpart we found from hard X-rays to the near-infrared, including 111 counterparts from the recent Gaia DR3 catalogue.

“…Situated on the south-western coast of Sicily, the Greek polis of Gela was founded by Rhodian colonists ca. 690 bc.50 Once a powerful city, Gela was sacked by the Carthaginians in 405 bc: its defences were levelled and the highly questionable (see Sidoli 2011). A date in the following century may be more appropriate: Netz 2020, 673 n. 78.…”

The Catalogus geometrarum from the Corpus Agrimensorum

The Catalogus geometrarum from the Corpus Agrimensorum, an early witness to the Aratean commentary tradition, names an author with mathematical interests as Euclid the Sicilian. If this individual is identical with Euclid the geometer, then we are able to move beyond the traditional biographies of Euclid, which rest on the problematic evidence of Proclus and Pappus, and consider an ancient case of mistaken identity which suggests that Euclid may even have been a Geloian by birth. This new identification raises questions about the status of Doric as a scientific language, and Alexandria’s role as a haven for those dislocated by war or civil strife, not merely as a magnet for scientific talent.
