Narrative:
Marshalled into gate by ground personnel. After arrival found damage to both aircraft. L1011 right wingtip contacted B757 left horizontal stabilizer. Ground personnel had given an all clear signal during the entire event. Supplemental information from acn 377347: ground crew disconnected and waived us off. The left engine was started first, but did not accelerate to idle - - engine was shut down. Began starting right engine with cold WX/high altitude unloaded procedure. About this time we heard an aircraft call to taxi into the gate behind us. Ramp asked if we could move up. We said 'no.' we didn't have an engine running yet. We heard the aircraft behind state that they had enough room to make it into gate with wing walkers. As right engine accelerated a slight bump was felt like a tow bar being disconnected. We thought we had possibly been taxied into (ground strike) operations was called and a visual inspection requested. 2 ramp personnel got on headset and inspected the aircraft. They visually and verbally assured us we were not hit and the aircraft was ok. We began a taxi out and left engine start. A question still remained and at about the same time ramp called and said they wanted us back for a closer inspection. Damage to the left elevator and lower left stabilizer was discovered. The L1011 right wing had passed under our left stabilizer making a 5 ft arc and taking a piece out of the left elevator trailing edge.
