No systematic description of the organization of the imperial household has come to hand. Scattered allusions reveal the presence of very numerous groups of officials, agents, and servants of all grades. Teachers, physicians, scholars, valets, chamberlains, butlers, cooks, kitchen servants, musicians, poets, generals, captains, guards, equerries, hostlers, herdsmen, elephant-drivers, and stablemen, ministers of state, judges, treasurers, secretaries, swarmed about the great halls and myriad chambers of the palaces at Agra, Delhi, and Fatehpur-Sikri. These, with the tradespeople who made their living by supplying the household but who were less directly attached to the emperor, constituted a migratory city of large size, which followed the emperor from residence to residence and in time of campaign swelled almost unbelievably the following of his enormous army. As for the court life which went on at the center of this vast and multi-colored setting, this was necessarily twofold, by that custom of all Moslem lands according to which the sexes must be segregated. Daily assemblages, gatherings at the mosques on Fridays, great ceremonies for special occasions, and the imperial hunts contained none but men as participants. If women saw any part of such festivities, it was from a distance and through thick veils or close-wrought lattices. Khondamir says that Humayun divided his attendants into three great classes, concerned respectively with government and war, with learning and literature, and with music and personal grace and beauty. The latter were called “people of pleasure ... because most people take great delight in the company of such young-looking men, of rosy cheeks and sweet voices, and are pleased by hearing their songs, and the pleasing sound of the musical instruments, such as the harp, the sackbut, and the lute.” Humayun devoted Sundays and Tuesdays to dealings with the first class, holding audience and attending to government duties on those days. Saturdays and Thursdays were days when “the tree of the hope” of literary and religious persons “produced the fruit of prosperity by their obtaining audience in the paradise-resembling court.” Mondays and Wednesdays were devoted to pleasure parties, when old companions and chosen friends were entertained by musicians and singers. On Fridays were convened “all the assemblies,” whatever this may mean; and the emperor sat with them as long as he could.
