Abstract [C I] emission in both the ^3^P_2_-^3^P_1_ and ^3^P_1_-^3^P_0_ ground- state fine-structure lines has been detected at a redshift of z = 2.286 in the protogalaxy IRAS F10214+4724. Like the CO emission observed in this source, the (C I] emission suggests that the line emission region is structured over spatial scales > 12". Estimates for the amount of molecular gas in the source are M(H_2_)~ 1 x 10^12^ h^-2^ to 2 x 10^13^ h^-2^ M_sun_, comparable to those based on CO data and comparable also to the total dynamical mass in the system. IRAS F10214+4724, a largely gaseous system bathed in ultraviolet light, exhibits the principal characteristics of a protogalaxy.
