Et voici les dimensions de l’autel en coudées, chaque coudée [valant] une coudée et une palme: la cavité est d’une coudée [de profondeur], plus une coudée de largeur, le rebord qui le limite à l’entour ayant un empan pour chaque face; tel est le support de l’autel.
Mishneh Torah, The Chosen Temple
The measurements of the Altar are very exact and its shape is known [by tradition] from man to man. The altar that those who ascended from the [Babylonian] exile built was made like the one which will be built in the future. It is forbidden to add or subtract from its dimensions.
Mishneh Torah, The Chosen Temple
The Altar that Moses made, that Solomon made, that the returnees of the [First] Exile made, and that will be made in the future are all 10 cubits high, and that which is stated in the Torah: "and three cubits its height, that is the place of the pyre alone (above the ledge of the Altar). And the dimensions of the Altar that the returnees of the Exile made and the one that will be built in the future are 32 cubits by 32 cubits.
