  We compare the properties of the stellar populations of the globular clusters
and field stars in two dwarf spheroidal galaxies (dSphs): ESO269-66, a near
neighbor of the giant S0 galaxy NGC 5128, and KKs3, one of the few extremely
isolated dSphs within 10 Mpc. The histories of star formation in these galaxies
are known from previous work on deep stellar photometry using images from the
Hubble Space Telescope (HST). The age and metal content for the nuclear
globular clusters in KKs3 and ESO269-66 are known from literature spectroscopic
studies: T=12.6 billion years, [Fe/H]=-1.5 and -1.55 dex. We use the Sersic
function to construct and analyze the profiles of the surface density of the
stars with high and low metallicities (red and blue) in KKs3 and ESO269-66, and
show that (1) the profiles of the density of red stars are steeper than those
of blue stars, which is indicative of gradients of metallicity and age in the
galaxies, and (2) the globular clusters in KKs3 and ESO269-66 contain roughly 4
and 40%, respectively, of all the old stars in the galaxies with metallicities
[Fe/H]~-1.5 to -1.6 dex and ages of 12-14 billion years. The globular clusters
are, therefore, relicts of the first, most powerful bursts of star formation in
the central regions of these objects. It is probable that, because of its
isolation, KKs3 has lost a smaller fraction of old low-metallicity stars than
ESO269-66.
