The Metrological Relief at Oxford

Abstract

Of peculiar interest among the Arundel marbles of the Pomfret donation at Oxford, is a slab in the shape of a pediment, ‘in which there is in basso relievo the figure of a man as big as the life with his arms extended as if he was crucified, but no lower than about his paps is seen, the cornice cutting him off as it were; and this extension of his arms is called a grecian measure, and over his arm is a grecian foot.’ The marble thus described by George Vertue, the engraver, was first published in Chandler's Marmora Oxoniensia, Pt. I., Pl. lix., No. 166, but its importance was completely overlooked until the late Prof. Matz, in one of his last papers, published a better drawing and pointed out the artistic interest of the relief as a sculpture belonging to a rather early period of Greek art. On the other hand, the merit of the monument as an authentic document of Greek metrology was set forth, at my request, by my friend Dr. Fr. Hultsch, the author of Griechische Metrologie, whose views are repeated in my Ancient Marbles in Great Britain. The chief result of his exposition was that our relief unites in a most interesting way the indication of the length of a fathom (ὀρλυιά) of 2·06 or 20·07 m. with that of a foot of 0·295 m., which is not, as one might expect, the sixth, but exactly the seventh part of the fathom. As such a division of the fathom does not agree with the well-known facts of Greek metrology, Hultsch imagined that the foot on our marble might rather be a modulus used by sculptors and architects, and he observed that the recent excavations of Olympia seem to show the dimensions of some of the temples, particularly of the very old temple of Heré, to be based on a double measure, on a foot but little longer (of 0·298 m.), as well as on a fathom of 2·084 m. which, again, corresponds to seven of those feet.
