An Etymological Dictionary of the German Language/Schrein
Schrein, m., ‘box, chest. shrine, coffin,’ from MidHG. schrîn, m. and n., ‘chest for clothes, money, or valuables, coffin,’ OHG. scrìni, n.; comp. the corresponding Du. schrijn, AS. scrîn, E. shrine, Scand. skrín. From Rom. and Lat. scrînium, ‘box, case for papers, &c., escritoire,’ whence also Ital. scrigno, ‘clothes-press,’ Fr. écrin, ‘casket.’ The diffusion of the term through the old West Teut. languages makes it probable that the Lat. word was borrowed at an early period, — contemporaneously with Arche, Kiste and Sack?.
