  We report the preparation and observation of single atoms of dysprosium in
arrays of optical tweezers with a wavelength of 532 nm imaged on the
intercombination line at 626 nm. We use the anisotropic light shift specific to
lanthanides and in particular a large difference in tensor and vector
polarizabilities between the ground and excited states to tune the differential
light shift and produce tweezers in near-magic or magic polarization. This
allows us to find a regime where single atoms can be produced and imaged. Using
the tweezer array toolbox to manipulate lanthanides will open new research
directions for quantum physics studies by taking advantage of their rich
spectrum, large spin and magnetic dipole moment.
