The article is mainly a recounting of the legend of the translation of the Pentateuch into Greek in the Letter of Aristeas, plus some later legends. It is substantially accurate, except that it takes the Letter of Aristeas at face value as recounting what actually happened. All indications are that it is a later legendary account whose historical value is at best unclear. For more on that, see here and links.
Nevertheless, I am always happy to see the Septuagint and the Old Testament Pseudepigrapha receiving media attention.
